List of Runtime Error Messages

This section lists some of the errors processed by the compiler runtime library (RTL).

NOTE:

To see the full list of runtime errors, see file ifcore_msg.msg, which is located in the libraries part of your kit.

For each error shown in the below table of example messages, you will see the error number, the severity code, error message text, and condition symbol name. Some messages also provide more details about the error.

To define the condition symbol values (PARAMETER statements) in your program, include the following file:

for_iosdef.for

As described in the table, the severity of the message determines which of the following occurs:

with info and warning, program execution continues
with error, the results may be incorrect
with severe, program execution stops (unless a recovery method is specified)

In the last case, to prevent program termination, you must include either an appropriate I/O error-handling specifier and recompile or, for certain errors, change the default action of a signal before you run the program again.

In the following table of example messages, the first column lists error numbers returned to IOSTAT variables when an I/O error is detected.

The first line of the second column provides the message as it is displayed (following forrtl:), including the severity level, message number, and the message text. The following lines of the second column contain the status condition symbol (such as FOR$IOS_INCRECTYP) and sometimes an explanation of the message.

In these messages, words in quotes represent variables. For example, "number" indicates a numeric variable, and "string" indicates a character string variable.

Number	Severity Level, Number, and Message Text; Condition Symbol and Explanation
1¹	severe (1): Not a Fortran-specific error FOR$IOS_NOTFORSPE. An error in the user program or in the RTL was not an Intel® Fortran-specific error and was not reportable through any other Intel® Fortran runtime messages.
2	severe (2): not implemented FOR$IOS_NOTIMP.
3	warning (3): ignored requested disposition FOR$IOS_IGNORED.
4	warning (4): ignored requested disposition, file not deleted FOR$IOS_IGNNOTDEL.
5	warning (5): requested disposition modified, file not deleted, unit "number", file "string" FOR$IOS_REQDISMOD.
8	severe (8): Internal consistency check failure FOR$IOS_BUG_CHECK. Internal error. Please check that the program is correct. Recompile if an error existed in the program. If this error persists, submit a problem report.
9	severe (9): Permission to access file denied FOR$IOS_PERACCFIL. Check the permissions of the specified file and whether the network device is mapped and available. Make sure the correct file and device was being accessed. Change the protection, specific file, or process used before rerunning the program.
10	severe (10): Cannot overwrite existing file FOR$IOS_CANOVEEXI. Specified file xxx already exists when OPEN statement specified STATUS='NEW' (create new file) using I/O unit `x`. Make sure correct file name, directory path, unit, and so forth were specified in the source program. Decide whether to: Rename or remove the existing file before rerunning the program. Modify the source file to specify different file specification, I/O unit, or OPEN statement STATUS.
11¹	info (11): Unit not connected FOR$IOS_UNINOTCON. The specified unit was not open at the time of the attempted I/O operation. Check if correct unit number was specified. If appropriate, use an OPEN statement to explicitly open the file (connect the file to the unit number).
14	info (14): SOURCE length "number" does not equal variable length "number" FOR$IOS_SOURCELENERR.
17	severe (17): Syntax error in NAMELIST input FOR$IOS_SYNERRNAM. The syntax of input to a namelist-directed READ statement was incorrect.
18	severe (18): Too many values for NAMELIST variable FOR$IOS_TOOMANVAL. An attempt was made to assign too many values to a variable during a namelist READ statement.
19	severe (19): Invalid reference to variable in NAMELIST input FOR$IOS_INVREFVAR. One of the following conditions occurred: The variable was not a member of the namelist group. An attempt was made to subscript a scalar variable. A subscript of the array variable was out-of-bounds. An array variable was specified with too many or too few subscripts for the variable. An attempt was made to specify a substring of a non-character variable or array name. A substring specifier of the character variable was out-of-bounds. A subscript or substring specifier of the variable was not an integer constant. An attempt was made to specify a substring by using an unsubscripted array variable.
20	severe (20): REWIND error FOR$IOS_REWERR. One of the following conditions occurred: The file was not a sequential file. The file was not opened for sequential or append access. The Intel® Fortran RTL I/O system detected an error condition during execution of a REWIND statement.
21	severe (21): Duplicate file specifications FOR$IOS_DUPFILSPE. Multiple attempts were made to specify file attributes without an intervening close operation. A DEFINE FILE statement was followed by another DEFINE FILE statement or an OPEN statement.
22	severe (22): Input record too long FOR$IOS_INPRECTOO. A record was read that exceeded the explicit or default record length specified when the file was opened. To read the file, use an OPEN statement with a RECL=VALUE (record length) of the appropriate size.
23	severe (23): BACKSPACE error FOR$IOS_BACERR. The Intel® Fortran RTL I/O system detected an error condition during execution of a BACKSPACE statement.
24¹	severe (24): End-of-file during read FOR$IOS_ENDDURREA. One of the following conditions occurred: An Intel® Fortran RTL I/O system end-of-file condition was encountered during execution of a READ statement that did not contain an END, ERR, or IOSTAT specification. An end-of-file record written by the ENDFILE statement was encountered during execution of a READ statement that did not contain an END, ERR, or IOSTAT specification. An attempt was made to read past the end of an internal file character string or array during execution of a READ statement that did not contain an END, ERR, or IOSTAT specification. This error is returned by END and ERRSNS.
25	severe (25): Record number outside range FOR$IOS_RECNUMOUT. A direct access READ, WRITE, or FIND statement specified a record number outside the range specified when the file was opened.
26	severe (26): OPEN or DEFINE FILE required FOR$IOS_OPEDEFREQ. A direct access READ, WRITE, or FIND statement was attempted for a file when no prior DEFINE FILE or OPEN statement with ACCESS='DIRECT' was performed for that file.
27	severe (27): Too many records in I/O statement FOR$IOS_TOOMANREC. An attempt was made to do one of the following: Read or write more than one record with an ENCODE or DECODE statement. Write more records than existed.
28	severe (28): CLOSE error FOR$IOS_CLOERR. An error condition was detected by the Intel® Fortran RTL I/O system during execution of a CLOSE statement.
29	severe (29): File not found FOR$IOS_FILNOTFOU. A file with the specified name could not be found during an OPEN operation.
30	severe (30): Open failure FOR$IOS_OPEFAI. An error was detected by the Intel® Fortran RTL I/O system while attempting to open a file in an OPEN, INQUIRE, or other I/O statement. This message is issued when the error condition is not one of the more common conditions for which specific error messages are provided. It can occur when an OPEN operation was attempted for one of the following: Segmented file that was not on a disk or a raw magnetic tape Standard I/O file that had been closed
31	severe (31): Mixed file access modes FOR$IOS_MIXFILACC. An attempt was made to use any of the following combinations: Formatted and unformatted operations on the same unit An invalid combination of access modes on a unit, such as direct and sequential An Intel® Fortran RTL I/O statement on a logical unit that was opened by a program coded in another language
32	severe (32): Invalid logical unit number FOR$IOS_INVLOGUNI. A logical unit number greater than 2,147,483,647 or less than zero was used in an I/O statement.
33	severe (33): ENDFILE error FOR$IOS_ENDFILERR. One of the following conditions occurred: The file was not a sequential organization file with variable-length records. The file was not opened for sequential, append, or direct access. An unformatted file did not contain segmented records. The Intel® Fortran RTL I/O system detected an error during execution of an ENDFILE statement.
34	severe (34): Unit already open FOR$IOS_UNIALROPE. A DEFINE FILE statement specified a logical unit that was already opened.
35	severe (35): Segmented record format error FOR$IOS_SEGRECFOR. An invalid segmented record control data word was detected in an unformatted sequential file. The file was probably either created with RECORDTYPE='FIXED' or 'VARIABLE' in effect, or was created by a program written in a language other than Fortran or Standard Fortran.
36	severe (36): Attempt to access non-existent record FOR$IOS_ATTACCNON. A direct-access READ or FIND statement attempted to access beyond the end of a relative file (or a sequential file on disk with fixed-length records) or access a record that was previously deleted from a relative file.
37	severe (37): Inconsistent record length FOR$IOS_INCRECLEN. An attempt was made to open a direct access file without specifying a record length.
38	severe (38): Error during write FOR$IOS_ERRDURWRI. The Intel® Fortran RTL I/O system detected an error condition during execution of a WRITE statement.
39	severe (39): Error during read FOR$IOS_ERRDURREA. The Intel® Fortran RTL I/O system detected an error condition during execution of a READ statement.
40	severe (40): Recursive I/O operation FOR$IOS_RECIO_OPE. While processing an I/O statement for a logical unit, another I/O operation on the same logical unit was attempted, such as a function subprogram that performs I/O to the same logical unit that was referenced in an expression in an I/O list or variable format expression.
41	severe (41): Insufficient virtual memory FOR$IOS_INSVIRMEM. The Intel® Fortran RTL attempted to exceed its available virtual memory while dynamically allocating space. To overcome this problem, investigate increasing the data limit. Before you try to run this program again, wait until the new system resources take effect. NOTE: This error can be returned by STAT in an ALLOCATE or a DEALLOCATE statement.
42	severe (42): No such device FOR$IOS_NO_SUCDEV. A pathname included an invalid or unknown device name when an OPEN operation was attempted.
43	severe (43): File name specification error FOR$IOS_FILNAMSPE. A pathname or file name given to an OPEN or INQUIRE statement was not acceptable to the Intel® Fortran RTL I/O system.
44	severe (44): Inconsistent record type FOR$IOS_INCRECTYP. The RECORDTYPE value in an OPEN statement did not match the record type attribute of the existing file that was opened.
45	severe (45): Keyword value error in OPEN statement FOR$IOS_KEYVALERR. An improper value was specified for an OPEN or CLOSE statement specifier requiring a value.
46	severe (46): Inconsistent OPEN/CLOSE parameters FOR$IOS_INCOPECLO. Specifications in an OPEN or CLOSE statement were inconsistent. Some invalid combinations follow: READONLY or ACTION='READ' with STATUS='NEW' or STATUS='SCRATCH' READONLY with STATUS='REPLACE', ACTION='WRITE', or ACTION='READWRITE' ACCESS='APPEND' with READONLY, ACTION='READ', STATUS='NEW', or STATUS='SCRATCH' DISPOSE='SAVE', 'PRINT', or 'SUBMIT' with STATUS='SCRATCH' DISPOSE='DELETE' with READONLY CLOSE statement STATUS='DELETE' with OPEN statement READONLY ACCESS='DIRECT' with POSITION='APPEND' or 'ASIS'
47	severe (47): Write to READONLY file FOR$IOS_WRIREAFIL. A write operation was attempted to a file that was declared ACTION='READ' or READONLY in the OPEN statement that is currently in effect.
48	severe (48): Invalid argument to Fortran Runtime Library FOR$IOS_INVARGFOR. The compiler passed an invalid or improperly coded argument to the Intel® Fortran RTL. This can occur if the compiler is newer than the RTL in use.
49	severe (49): invalid key specification, unit "number", file "string" FOR$IOS_INVKEYSPE.
50	severe (50): inconsistent key change or duplicate key, unit "number", file "string" FOR$IOS_INCKEYCHG.
51	severe (51): Inconsistent file organization FOR$IOS_INCFILORG. The file organization specified in an OPEN statement did not match the organization of the existing file.
52	severe (52): specified record locked, unit "number", file "string" FOR$IOS_SPERECLOC.
53	severe (53): No current record, unit "number", file "string" FOR$IOS_NO_CURREC. Attempted to execute a REWRITE statement to rewrite a record when the current record was undefined. To define the current record, execute a successful READ statement. You can optionally perform an INQUIRE statement on the logical unit after the READ statement and before the REWRITE statement. No other operations on the logical unit may be performed between the READ and REWRITE statements.
54	severe (54): REWRITE error, unit "number", file "string" FOR$IOS_REWRITERR.
55	severe (55): DELETE error, unit "number", file "string" FOR$IOS_DELERR. An error condition was detected by the Intel® Fortran RTL I/O system during execution of a DELETE statement.
56	severe (56): UNLOCK error, unit "number", file "string" FOR$IOS_UNLERR.
57	severe (57): FIND error, unit "number", file "string" FOR$IOS_FINERR. The Intel® Fortran RTL I/O system detected an error condition during execution of a FIND statement.
58¹	info (58): Format syntax error at or near xx FOR$IOS_FMTSYN. Check the statement containing `xx`, a character substring from the format string, for a format syntax error. For more information, see the FORMAT statement.
59	severe (59): List-directed I/O syntax error FOR$IOS_LISIO_SYN. The data in a list-directed input record had an invalid format, or the type of the constant was incompatible with the corresponding variable. The value of the variable was unchanged. NOTE: Note: The ERR transfer is taken after completion of the I/O statement for error number 59. The resulting file status and record position are the same as if no error had occurred. However, other I/O errors take the ERR transfer as soon as the error is detected, so file status and record position are undefined.
60	severe (60): Infinite format loop FOR$IOS_INFFORLOO. The format associated with an I/O statement that included an I/O list had no field descriptors to use in transferring those values.
61	severe or info(61): Format/variable-type mismatch FOR$IOS_FORVARMIS. An attempt was made either to read or write a real variable with an integer field descriptor (I, L, O, Z, B), or to read or write an integer or logical variable with a real field descriptor (D, E, or F). To suppress this error message, see the description of check[:]noformat. NOTE: Note: The severity depends on the check[:]keywords option used during the compilation command. The ERR transfer is taken after completion of the I/O statement for error numbers 61, 63, 64, and 68. The resulting file status and record position are the same as if no error had occurred. However, other I/O errors take the ERR transfer as soon as the error is detected, so file status and record position are undefined.
62	severe (62): Syntax error in format FOR$IOS_SYNERRFOR. A syntax error was encountered while the RTL was processing a format stored in an array or character variable.
63	error or info(63): Output conversion error FOR$IOS_OUTCONERR. During a formatted output operation, the value of a particular number could not be output in the specified field length without loss of significant digits. When this situation is encountered, the overflowed field is filled with asterisks to indicate the error in the output record. If no ERR address has been defined for this error, the program continues after the error message is displayed. To suppress this error message, see the description of check[:]nooutput_conversion. NOTE: Note: The severity depends on the check[:]keywords option used during the compilation command. The ERR transfer is taken after completion of the I/O statement for error numbers 61, 63, 64, and 68. The resulting file status and record position are the same as if no error had occurred. However, other I/O errors take the ERR transfer as soon as the error is detected, so file status and record position are undefined.
64	severe (64): Input conversion error FOR$IOS_INPCONERR. During a formatted input operation, an invalid character was detected in an input field, or the input value overflowed the range representable in the input variable. The value of the variable was set to zero. NOTE: The ERR transfer is taken after completion of the I/O statement for error numbers 61, 63, 64, and 68. The resulting file status and record position are the same as if no error had occurred. However, other I/O errors take the ERR transfer as soon as the error is detected, so file status and record position are undefined.
65	error (65): Floating invalid FOR$IOS_FLTINV. During an arithmetic operation, the floating-point values used in a calculation were invalid for the type of operation requested or invalid exceptional values. For example, the error can occur if you request a log of the floating-point values 0.0 or a negative number. For certain arithmetic expressions, specifying the check[:]nopower option can suppress this message.
66	severe (66): Output statement overflows record FOR$IOS_OUTSTAOVE. An output statement attempted to transfer more data than would fit in the maximum record size.
67	severe (67): Input statement requires too much data FOR$IOS_INPSTAREQ. Attempted to read more data than exists in a record with an unformatted READ statement or with a formatted sequential READ statement from a file opened with a PAD='NO' specifier.
68	severe (68): Variable format expression value error FOR$IOS_VFEVALERR. The value of a variable format expression was not within the range acceptable for its intended use; for example, a field width was less than or equal to zero. A value of 1 was assumed, except for a P edit descriptor, for which a value of zero was assumed. NOTE: The ERR transfer is taken after completion of the I/O statement for error numbers 61, 63, 64, and 68. The resulting file status and record position are the same as if no error had occurred. However, other I/O errors take the ERR transfer as soon as the error is detected, so file status and record position are undefined.
69¹	error (69): Process interrupted (SIGINT) FOR$IOS_SIGINT. The process received the signal SIGINT. Determine source of this interrupt signal (described in signal(3)).
70¹	severe (70): Integer overflow FOR$IOS_INTOVF. During an arithmetic operation, an integer value exceeded byte, word, or longword range. The result of the operation was the correct low-order part. Consider specifying a larger integer data size (modify source program or, for an INTEGER declaration, possibly use the integer-size[:]size option).
71¹	severe (71): Integer divide by zero FOR$IOS_INTDIV. During an integer arithmetic operation, an attempt was made to divide by zero. The result of the operation was set to the dividend, which is equivalent to division by 1.
72¹	error (72): Floating overflow FOR$IOS_FLTOVF. During an arithmetic operation, a floating-point value exceeded the largest representable value for that data type. See Data Representation for ranges of the various data types.
73¹	error (73): Floating divide by zero FOR$IOS_FLTDIV. During a floating-point arithmetic operation, an attempt was made to divide by zero.
74¹	error (74): Floating underflow FOR$IOS_FLTUND. During an arithmetic operation, a floating-point value became less than the smallest finite value for that data type. Depending on the values of the fpe[:]`n` option, the underflowed result was either set to zero or allowed to gradually underflow. See the Data Representation for ranges of the various data types.
75¹	error (75): Floating point exception FOR$IOS_SIGFPE. A floating-point exception occurred. Possible causes include: Division by zero. Overflow. An invalid operation, such as subtraction of infinite values, multiplication of zero by infinity without signs), division of zero by zero or infinity by infinity. Conversion of floating-point to fixed-point format when an overflow prevents conversion.
76¹	error (76): IOT trap signal FOR$IOS_SIGIOT. Core dump file created. Examine core dump for possible cause of this `IOT` signal.
77¹	severe (77): Subscript out of range FOR$IOS_SUBRNG. An array reference was detected outside the declared array bounds.
78¹	error (78): Process killed FOR$IOS_SIGTERM. The process received a signal requesting termination of this process. Determine the source of this software termination signal.
79¹	error (79): Process quit FOR$IOS_SIGQUIT. The process received a signal requesting termination of itself. Determine the source of this quit signal.
80¹	severe (80): wrong number of arguments FOR$IOS_WRONUMARG.
81¹	severe (81): invalid argument to math library FOR$IOS_INVARGMAT.
82¹	severe (82): undefined exponentiation FOR$IOS_UNDEXP.

84¹	severe (84): square root of negative value FOR$IOS_SQUROONEG.
85¹	info (85): output conversion overflows field, unit "number", file "string" FOR$IOS_OUTCONOVE.
87¹	severe (87): significance lost in math library FOR$IOS_SIGLOSMAT.
88¹	severe (88): floating overflow in math library FOR$IOS_FLOOVEMAT.
89 ¹	error (89): floating underflow in math library FOR$IOS_FLOUNDMAT.
90¹	info (90): INQUIRE of internal unit-number is always an error (NOTE: unit identifies a file) FOR$IOS_IOSTAT_INTERNAL. The file name specified for an INQUIRE statement is an internal unit-number.
91¹	info (91): INQUIRE of internal unit-number is always an error (NOTE: unit does not identify a file) FOR$IOS_IOSTAT_INTERNAL_UNIT. The unit number specified for an INQUIRE statement is an internal unit-number.
93	severe (93): adjustable array dimension error FOR$IOS_ADJARRDIM.
94	severe (94): invalid key match specifier for key direction, unit "number", file "string" FOR$IOS_INVMATKEY .
95¹	info (95): Floating-point conversion failed FOR$IOS_FLOCONFAI. The attempted unformatted read or write of non-native floating-point data failed because the floating-point value: Exceeded the allowable maximum value for the equivalent native format and was set equal to infinity (plus or minus). Was infinity (plus or minus) and was set to infinity (plus or minus). Was invalid and was set to not a number (NaN). Very small numbers are set to zero (0). This error could be caused by the specified non-native floating-point format not matching the floating-point format found in the specified file. Check the following: The correct file was specified. The record layout matches the format Intel® Fortran is expecting. The ranges for the data being used (see Data Representation). The correct non-native floating-point data format was specified (see Supported Native and Non-native Numeric Formats).
96	info (96): F_UFMTENDIAN environment variable was ignored:erroneous syntax FOR$IOS_UFMTENDIAN. Syntax for specifying whether little endian or big endian conversion is performed for a given Fortran unit was incorrect. Even though the program will run, the results might not be correct if you do not change the value of `F_UFMTENDIAN`. For correct syntax, see Environment Variable F_UFMTENDIAN Method.
97	severe (97): write exceeds the record length of the file, unit "number", file "string" FOR$IOS_WRIEXCEEDRECL.
98	severe (98): cannot allocate memory for the file buffer - out of memory FOR_S_NOMEMFORIO. This error often occurs during a file I-O operation such as OPEN, READ, or WRITE. Either increase the amount of memory available to the program, or reduce its demand.
99	severe (99): FORT_FMT_RECL environment variable has erroneous syntax FOR$IOS_INVFMTRECL.

117	severe (117): If NEWUNIT appears in OPEN statement either FILE or STATUS (with value SCRATCH) specifier shall appear FOR$IOS_FILE_OR_SCRATCH.
118	severe (118): The 'RECL=' value in an OPEN statement exceeds the maximum allowed for the file's record type. FOR$IOS_MAX_FXD_RECL. The 'RECL=' value in an OPEN statement is too large for the file’s record type.
119¹	severe (119): The FORT_BUFFERING_THRESHOLD environment variable has erroneous syntax FOR$ IOS_INVTHRESHOLD. If specified, the FORT_BUFFERING_THRESHOLD environment variable must be an integer value greater than zero and less than 2147483647.
120	severe (120): Operation requires seek ability FOR$IOS_OPEREQSEE. Attempted an operation on a file that requires the ability to perform seek operations on that file. Make sure the correct unit, directory path, and file were specified.
121	severe (121): Cannot access current working directory FOR$IOS_CWDERROR. Cannot access the current working directory to open or access a file. One of the following conditions occurred: The directory has been deleted or moved by another task. The getcwd system function failed due to an OS or file-system problem.

126	severe (126): A non-advancing READ immediately following a non-advancing WRITE on the same unit number is not allowed, unit "number" FOR$IOS_NONADV_READ_AFTER_WRITE.
127	severe (127): User Defined I/O procedure returned error <user-iostat, message: '<user-iomsg>' FOR$IOS_UDIO_CHILD_IOSTAT_IOMSG. A child I/O action has set the IOMSG and IOSTAT shown in this message.
128	info (128): Error stop – program terminated FOR$IOS_ERROR_STOP. The user program has executed an ERROR STOP statement.
129	info (129): User Defined I/O procedure's IOMSG was truncated to fit IOMSG variable FOR$IOS_UDIO_IOMSG_TRUNCATED. A child I/O action has set IOMSG and IOSTAT. The result was too large to be held by the parent's IOMSG variable; non-blank text has been truncated.
138¹	severe (138): Array index out of bounds FOR$IOS_BRK_RANGE. An array subscript is outside the dimensioned boundaries of that array. Set the check[:]bounds option and recompile.
139¹	severe: (139): Array index out of bounds for index "number" FOR$IOS_BRK_RANGE2. An array subscript is outside the dimensioned boundaries of that array. Set the check[:]bounds option and recompile.
140¹	error (140): Floating inexact FOR$IOS_FLTINE. A floating-point arithmetic or conversion operation gave a result that differs from the mathematically exact result. This trap is reported if the rounded result of an IEEE operation is not exact.
144¹	severe (144): Reserved operand FOR$IOS_ROPRAND. The Intel® Fortran RTL encountered a reserved operand while executing your program. Please report the problem to Intel.
145¹	severe (145): Assertion error FOR$IOS_ASSERTERR. The Intel® Fortran RTL encountered an assertion error. Please report the problem to Intel.

A subnormalized number is smaller than the lowest value in the normal range for the data type specified. See Data Representation for ranges for floating-point types. Either locate and correct the source code causing the subnormalized value or, if a subnormalized value is acceptable, specify a different value for the fpe compiler option to allow program continuation.
163¹	severe (163): Program Exception - floating stack check FOR$IOS_PGM_FLTSTK. During a floating-point operation, the floating-point register stack on systems using IA-32 architecture overflowed or underflowed. This is a fatal exception. The most likely cause is calling a REAL function as if it were an INTEGER function or subroutine, or calling an INTEGER function or subroutine as if it were a REAL function. Carefully check that the calling code and routine being called agree as to how the routine is declared. If you are unable to resolve the issue, please send a problem report with an example to Intel.
164¹	severe (164): Program Exception - integer divide by zero FOR$IOS_PGM_INTDIV. During an integer arithmetic operation, an attempt was made to divide by zero. Locate and correct the source code causing the integer divide by zero.

542	severe (542): Label not found in assigned GOTO list FOR$IOS_F6098. The label assigned to the integer-variable name was not specified in the label list of the assigned GOTO statement.
543	severe (543): INTEGER arithmetic overflow FOR$IOS_F6099. This error occurs whenever integer arithmetic results in overflow.
544	severe (544): INTEGER overflow on input FOR$IOS_F6100. An integer item exceeded the legal size limits. An INTEGER (1) item must be in the range -127 to 128. An INTEGER (2) item must be in the range -32,767 to 32,768. An INTEGER (4) item must be in the range -2,147,483,647 to 2,147,483,648.
545	severe (545): Invalid INTEGER FOR$IOS_F6101. Either an illegal character appeared as part of an integer, or a numeric character larger than the radix was used in an alternate radix specifier.
546	severe (546): REAL indefinite (uninitialized or previous error) FOR$IOS_F6102. An invalid real number was read from a file, an internal variable, or the console. This can happen if an invalid number is generated by passing an illegal argument to an intrinsic function -- for example, SQRT(-1) or ASIN(2). If the invalid result is written and then later read, the error will be generated.
547	severe (547): Invalid REAL FOR$IOS_F6103. An illegal character appeared as part of a real number.
548	severe (548): REAL math overflow FOR$IOS_F6104. A real value was too large. Floating-point overflows in either direct or emulated mode generate NaN (Not-A-Number) exceptions, which appear in the output field as asterisks (*) or the letters NAN.
549	severe (549): No matching CASE found for SELECT CASE FOR$IOS_F6105.
550	severe (550): INTEGER assignment overflow FOR$IOS_F6106. This error occurs when assignment to an integer is out of range.
551	severe (551): Formatted I/O not consistent with OPEN options FOR$IOS_F6200. The program tried to perform formatted I/O on a unit opened with FORM='UNFORMATTED' or FORM='BINARY'.
552	severe (552): List-directed I/O not consistent with OPEN options FOR$IOS_F6201. The program tried to perform list-directed I/O on a file that was not opened with FORM='FORMATTED' and ACCESS='SEQUENTIAL'.
553	severe (553): Terminal I/O not consistent with OPEN options FOR$IOS_F6202. When a special device such as CON, LPT1, or PRN is opened in an OPEN statement, its access must be sequential and its format must be either formatted or binary. By default ACCESS='SEQUENTIAL' and FORM='FORMATTED' in OPEN statements. To generate this error the device's OPEN statement must contain an option not appropriate for a terminal device, such as ACCESS='DIRECT' or FORM='UNFORMATTED'.
554	severe (554): Direct I/O not consistent with OPEN options FOR$IOS_F6203. A REC=`option` was included in a statement that transferred data to a file that was opened with the ACCESS='SEQUENTIAL' option.
555	severe (555): Unformatted I/O not consistent with OPEN options FOR$IOS_F6204. If a file is opened with FORM='FORMATTED', unformatted or binary data transfer is prohibited.
556	severe (556): A edit descriptor expected for CHARACTER FOR$IOS_F6205. The A edit descriptor was not specified when a character data item was read or written using formatted I/O.
557	severe (557): E, F, D, or G edit descriptor expected for REAL FOR$IOS_F6206. The E, F, D, or G edit descriptor was not specified when a real data item was read or written using formatted I/O.
558	severe (558): I edit descriptor expected for INTEGER FOR$IOS_F6207. The I edit descriptor was not specified when an integer data item was read or written using formatted I/O.
559	severe (559): L edit descriptor expected for LOGICAL FOR$IOS_F6208. The L edit descriptor was not specified when a logical data item was read or written using formatted I/O.
560	severe (560): File already open: parameter mismatch FOR$IOS_F6209. An OPEN statement specified a connection between a unit and a filename that was already in effect. In this case, only the BLANK= specifier can have a different setting.
561	severe (561): Namelist I/O not consistent with OPEN options FOR$IOS_F6210. The program tried to perform namelist I/O on a file that was not opened with FORM='FORMATTED' and ACCESS='SEQUENTIAL'.
562	severe (562): IOFOCUS option illegal with non-window unit FOR$IOS_F6211. IOFOCUS was specified in an OPEN or INQUIRE statement for a non-window unit. The IOFOCUS option can only be used when the unit opened or inquired about is a QuickWin child window.
563	severe (563): IOFOCUS option illegal without QuickWin FOR$IOS_F6212. IOFOCUS was specified in an OPEN or INQUIRE statement for a non-QuickWin application. The IOFOCUS option can only be used when the unit opened or inquired about is a QuickWin child window.
564	severe (564): TITLE illegal with non-window unit FOR$IOS_F6213. TITLE was specified in an OPEN or INQUIRE statement for a non-window unit. The TITLE option can only be used when the unit opened or inquired about is a QuickWin child window.
565	severe (565): TITLE illegal without QuickWin FOR$IOS_F6214. TITLE was specified in an OPEN or INQUIRE statement for a non-QuickWin application. The TITLE option can only be used when the unit opened or inquired about is a QuickWin child window.
566	severe (566): KEEP illegal for scratch file FOR$IOS_F6300. STATUS='KEEP' was specified for a scratch file. This is illegal because scratch files are automatically deleted at program termination.
567	severe (567): SCRATCH illegal for named file FOR$IOS_F6301. STATUS='SCRATCH' should not be used in a statement that includes a filename.
568	severe (568): Multiple radix specifiers FOR$IOS_F6302. More than one alternate radix for numeric I/O was specified. F6302 can indicate an error in spacing or a mismatched format for data of different radices.
569	severe (569): Illegal radix specifier FOR$IOS_F6303. A radix specifier was not between 2 and 36, inclusive. Alternate radix constants must be of the form n#ddd... where n is a radix from 2 to 36 inclusive and ddd... are digits with values less than the radix. For example, 3#12 and 34#7AX are valid constants with valid radix specifiers. 245#7A and 39#12 do not have valid radix specifiers and generate error 569 if input.
570	severe (570): Illegal STATUS value FOR$IOS_F6304. An illegal value was used with the STATUS option. STATUS accepts the following values: 'KEEP' or 'DELETE'' when used with CLOSE statements 'OLD', 'NEW', 'SCRATCH', or 'UNKNOWN' when used with OPEN statements
571	severe (571): Illegal MODE value FOR$IOS_F6305. An illegal value was used with the MODE option. MODE accepts the values 'READ', 'WRITE', or 'READWRITE'.
572	severe (572): Illegal ACCESS value FOR$IOS_F6306. An illegal value was used with the ACCESS option. ACCESS accepts the values 'SEQUENTIAL' and 'DIRECT'.
573	severe (573): Illegal BLANK value FOR$IOS_F6307. An illegal value was used with the BLANK option. BLANK accepts the values 'NULL' and 'ZERO'.
574	severe (574): Illegal FORM value FOR$IOS_F6308. An illegal value was used with the FORM option. FORM accepts the following values: 'FORMATTED', 'UNFORMATTED', and 'BINARY'.
575	severe (575): Illegal SHARE value FOR$IOS_F6309. An illegal value was used with the SHARE option. SHARE accepts the values 'COMPAT', 'DENYRW', 'DENYWR', 'DENYRD', and 'DENYNONE'.
576	severe (576): illegal LOCKMODE value FOR$IOS_F6310.
577	severe (577): Illegal record number FOR$IOS_F6311. An invalid number was specified as the record number for a direct-access file. The first valid record number for direct-access files is 1.
578	severe (578): No unit number associated with * FOR$IOS_F6312. In an INQUIRE statement, the NUMBER option was specified for the file associated with * (console).
579	severe (579): illegal RECORDS value FOR$IOS_F6313.
580	severe (580): Illegal unit number FOR$IOS_F6314. An illegal unit number was specified. Legal unit numbers can range from 0 through 2**31-1, inclusive.
581	severe (581): Illegal RECL value FOR$IOS_F6315. A negative or zero record length was specified for a direct file. The smallest valid record length for direct files is 1.
582	severe (582): Array already allocated FOR$IOS_F6316. The program attempted to ALLOCATE an already allocated array.
583	severe (583): Array size zero or negative FOR$IOS_F6317. The size specified for an array in an ALLOCATE statement must be greater than zero.
584	severe (584): Non-HUGE array exceeds 64K FOR$IOS_F6318.
585	severe (585): Array not allocated FOR$IOS_F6319. The program attempted to DEALLOCATE an array that was never allocated.
586	severe (586): BACKSPACE illegal on terminal device FOR$IOS_F6400. A BACKSPACE statement specified a unit connected to a terminal device such as a terminal or printer.
587	severe (587): EOF illegal on terminal device FOR$IOS_F6401. An EOF intrinsic function specified a unit connected to a terminal device such as a terminal or printer.
588	severe (588): ENDFILE illegal on terminal device FOR$IOS_F6402. An ENDFILE statement specified a unit connected to a terminal device such as a terminal or printer.
589	severe (589): REWIND illegal on terminal device FOR$IOS_F6403. A REWIND statement specified a unit connected to a terminal device such as a terminal or printer.
590	severe (590): DELETE illegal for read-only file FOR$IOS_F6404. A CLOSE statement specified STATUS='DELETE' for a read-only file.
591	severe (591): External I/O illegal beyond end of file FOR$IOS_F6405. The program tried to access a file after executing an ENDFILE statement or after it encountered the end-of-file record during a read operation. A BACKSPACE, REWIND, or OPEN statement must be used to reposition the file before execution of any I/O statement that transfers data.
592	severe (592): Truncation error: file closed FOR$IOS_F6406.
593	severe (593): Terminal buffer overflow FOR$IOS_F6407. More than 131 characters were input to a record of a unit connected to the terminal (keyboard). Note that the operating system may impose additional limits on the number of characters that can be input to the terminal in a single record.
594	severe (594): Comma delimiter disabled after left repositioning FOR$IOS_F6408. If you have record lengths that exceed the buffer size associated with the record, (for instance, the record is a file with the buffer set by BLOCKSIZE in the OPEN statement), either you should not do left tabbing within the record, or you should not use commas as field delimiters. This is because commas are disabled as input field delimiters if left tabbing leaves the record positioned in a previous buffer. For example, consider you have a file LONG.DAT that is one continuous record with data fields separated by commas. You then set the buffer associated with the file to 512 bytes, read more than one buffer size of data, tab left to data in the previous buffer, and attempt to read further data, as follows: INTEGER value(300) OPEN (1, FILE = 'LONG.DAT', BLOCKSIZE = 512)s READ (1, 100) (value(i), i = 1, 300)s 100 FORMAT (290I2,TL50,10I2) In this case, error 594 occurs.
595	severe (595): LOCKING illegal on sequential file FOR$IOS_F6409.
596	severe (596): file already locked or unlocked FOR$IOS_F6410.
597	severe (597): file deadlocked FOR$IOS_F6411.
599	severe (599): File already connected to a different unit FOR$IOS_F6413. The program tried to connect an already connected file to a new unit. A file can be connected to only one unit at a time.
600	severe (600): Access not allowed FOR$IOS_F6414. This error can be caused by one of the following: The filename specified in an OPEN statement was a directory. An OPEN statement tried to open a read-only file for writing. The file was opened with SHARE='DENYRW' by another process.
601	severe (601): File already exists FOR$IOS_F6415. An OPEN statement specified STATUS='NEW' for a file that already exists.
602	severe (602): File not found FOR$IOS_F6416. An OPEN statement specified STATUS='OLD' for a specified file or a directory path that does not exist.
603	severe (603): Too many open files FOR$IOS_F6417. The program exceeded the number of open files the operating system allows.
604	severe (604): Too many units connected FOR$IOS_F6418. The program exceeded the number of units that can be connected at one time. Units are connected with the OPEN statement.
605	severe (605): Illegal structure for unformatted file FOR$IOS_F6419. The file was opened with FORM='UNFORMATTED' and ACCESS='SEQUENTIAL', but its internal physical structure was incorrect or inconsistent. Possible causes: the file was created in another mode or by a non-Fortran program.
606	severe (606): Unknown unit number FOR$IOS_F6420. A statement such as BACKSPACE or ENDFILE specified a file that had not yet been opened. (The READ and WRITE statements do not cause this problem because they prompt you for a file if the file has not been opened yet.)
607	severe (607): File read-only or locked against writing FOR$IOS_F6421. The program tried to transfer data to a file that was opened in read-only mode or locked against writing. The error message may indicate a CLOSE error when the fault is actually coming from WRITE. This is because the error is not discovered until the program tries to write buffered data when it closes the file.
608	severe (608): No space left on device FOR$IOS_F6422. The program tried to transfer data to a file residing on a device (such as a hard disk) that was out of storage space.
609	severe (609): Too many threads FOR$IOS_F6423. Too many threads were active simultaneously. At most, 32 threads can be active at one time. Close any unnecessary processes or child windows within your application.
610	severe (610): Invalid argument FOR$IOS_F6424.
611	severe (611): BACKSPACE illegal for SEQUENTIAL write-only files FOR$IOS_F6425. The BACKSPACE statement is not allowed in files opened with MODE='WRITE' (write-only status) because BACKSPACE requires reading the previous record in the file to provide positioning. Resolve the problem by giving the file read access or by avoiding the BACKSPACE statement. Note that the REWIND statement is valid for files opened as write-only.
612	severe (612): File not open for reading or file locked FOR$IOS_F6500. The program tried to read from a file that was not opened for reading or was locked.
613	severe (613): End of file encountered FOR$IOS_F6501. The program tried to read more data than the file contains.
614	severe (614): Positive integer expected in repeat field FOR$IOS_F6502. When the `ic` form is used in list-directed input, the `i` must be a positive integer. For example, consider the following statement: READ(,) a, b Input 256.7 is accepted, but input 2.1*56.7 returns error 614.
615	severe (615): Multiple repeat field FOR$IOS_F6503. In list-directed input of the form `ic`, an extra repeat field was used. For example, consider the following: READ(,) I, J, K Input of 213 returns this error. The 21 means send two values, each 1; the *3 is an error.
616	severe (616): Invalid number in input FOR$IOS_F6504. Some of the values in a list-directed input record were not numeric. For example, consider the following: READ(,) I, J The preceding statement would cause this error if the input were: 123 'abc'.
617	severe (617): Invalid string in input FOR$IOS_F6505. A string item was not enclosed in single quotation marks.
618	severe (618): Comma missing in COMPLEX input FOR$IOS_F6506. When using list-directed input, the real and imaginary components of a complex number were not separated by a comma.
619	severe (619): T or F expected in LOGICAL read FOR$IOS_F6507. The wrong format was used for the input field for logical data. The input field for logical data consists of optional blanks, followed by an optional decimal point, followed by a T for true or F for false. The T or F may be followed by additional characters in the field, so that .TRUE. and .FALSE. are acceptable input forms.
620	severe (620): Too many bytes read from unformatted record FOR$IOS_F6508. The program tried to read more data from an unformatted file than the current record contained. If the program was reading from an unformatted direct file, it tried to read more than the fixed record length as specified by the RECL option. If the program was reading from an unformatted sequential file, it tried to read more data than was written to the record.
621	severe (621): H or apostrophe edit descriptor illegal on input FOR$IOS_F6509. Hollerith (H) or apostrophe edit descriptors were encountered in a format used by a READ statement.
622	severe (622): Illegal character in hexadecimal input FOR$IOS_F6510. The input field contained a character that was not hexadecimal. Legal hexadecimal characters are 0 - 9 and A - F.
623	severe (623): Variable name not found FOR$IOS_F6511. A name encountered on input from a namelist record is not declared in the corresponding NAMELIST statement.
624	severe (624): Invalid NAMELIST input format FOR$IOS_F6512. The input record is not in the correct form for NAMELIST input.
625	severe (625): Wrong number of array dimensions FOR$IOS_F6513. In NAMELIST input, an array name was qualified with a different number of subscripts than its declaration, or a non-array name was qualified.
626	severe (626): Array subscript exceeds allocated area FOR$IOS_F6514. A subscript was specified in NAMELIST input which exceeded the declared dimensions of the array.
627	severe (627): Invalid subrange in NAMELIST input FOR$IOS_F6515. A character item in namelist input was qualified with a subrange that did not meet the requirement that 1 <= e1 <= e2 <= len (where "len" is the length of the character item, "e1" is the leftmost position of the substring, and "e2" is the rightmost position of the substring).
628	severe (628): Substring range specified on non-CHARACTER item FOR$IOS_F6516. A non-CHARACTER item in namelist input was qualified with a substring range.
629	severe (629): Internal file overflow FOR$IOS_F6600. The program either overflowed an internal-file record or tried to write to a record beyond the end of an internal file.
630	severe (630): Direct record overflow FOR$IOS_F6601. The program tried to write more than the number of bytes specified in the RECL option to an individual record of a direct-access file.
631	severe (631):Numeric field bigger than record size FOR$IOS_F6602. The program tried to write a non-CHARACTER item across a record boundary in list-directed or namelist output. Only character constants can cross record boundaries.
632	severe (632): Heap space limit exceeded FOR$IOS_F6700. The program ran out of heap space. The ALLOCATE statement and various internal functions allocate memory from the heap. This error will be generated when the last of the heap space is used up.
633	severe (633): Scratch file name limit exceeded FOR$IOS_F6701. The program exhausted the template used to generate unique scratch-file names. The maximum number of scratch files that can be open at one time is 26.
634	severe (634): D field exceeds W field in ES edit descriptor FOR$IOS_F6970. The specified decimal length `d` exceeds the specified total field width `w` in an ES edit descriptor.
635	severe (635): D field exceeds W field in EN edit descriptor FOR$IOS_F6971. The specified decimal length `d` exceeds the specified total field width `w` in an EN edit descriptor.
636	severe (636): Exponent of 0 not allowed in format FOR$IOS_F6972.
637	severe (637): Integer expected in format FOR$IOS_F6980. An edit descriptor lacked a required integer value. For example, consider the following: WRITE(*, 100) I, J 100 FORMAT (I2, TL, I2) The preceding code will cause this error because an integer is expected after TL.
638	severe (638): Initial left parenthesis expected in format FOR$IOS_F6981. A format did not begin with a left parenthesis ( ( ).
639	severe (639): Positive integer expected in format FOR$IOS_F6982. A zero or negative integer value was used in a format. Negative integer values can appear only with the P edit descriptor. Integer values of 0 can appear only in the `d` and `m` fields of numeric edit descriptors.
640	severe (640): Repeat count on nonrepeatable descriptor FOR$IOS_F6983. One or more BN, BZ, S, SS, SP, T, TL, TR, /, $, :, or apostrophe (') edit descriptors had repeat counts associated with them.
641	severe (641): Integer expected preceding H, X, or P edit descriptor FOR$IOS_F6984. An integer did not precede a (nonrepeatable) H, X, or P edit descriptor. The correct formats for these descriptors are `nH`, `nX`, and `kP`, respectively, where `n` is a positive integer and `k` is an optionally signed integer.
642	severe (642): N or Z expected after B in format FOR$IOS_F6985. To control interpretation of embedded and trailing blanks within numeric input fields, you must specify BN (to ignore them) or BZ (to interpret them as zeros).
643	severe (643): Format nesting limit exceeded FOR$IOS_F6986. More than sixteen sets of parentheses were nested inside the main level of parentheses in a format.
644	severe (644): '.' expected in format FOR$IOS_F6987. No period appeared between the `w` and `d` fields of a D, E, F, or G edit descriptor.
645	severe (645): Unexpected end of format FOR$IOS_F6988. An incomplete format was used. Improperly matched parentheses, an unfinished Hollerith (H) descriptor, or another incomplete descriptor specification can cause this error.
646	severe (646): Unexpected character in format FOR$IOS_F6989. A character that cannot be interpreted as part of a valid edit descriptor was used in a format. For example, consider the following: WRITE(*, 100) I, J 100 FORMAT (I2, TL4.5, I2) The code will generate this error because TL4.5 is not a valid edit descriptor. An integer must follow TL.
647	severe (647): M field exceeds W field in I edit descriptor FOR$IOS_F6990. In syntax I`w.m`, the value of `m` cannot exceed the value of `w`.
648	severe (648): Integer out of range in format FOR$IOS_F6991. An integer value specified in an edit descriptor was too large to represent as a 4-byte integer.
649	severe (649): format not set by ASSIGN FOR$IOS_F6992. The format specifier in a READ, WRITE, or PRINT statement was an integer variable, but an ASSIGN statement did not properly assign it the statement label of a FORMAT statement in the same program unit.
650	severe (650): Separator expected in format FOR$IOS_F6993. Within format specifications, edit descriptors must be separated by commas or slashes (/).
651	severe (651): %c or $: nonstandard edit descriptor in format FOR$IOS_F6994.
652	severe (652): Z: nonstandard edit descriptor in format FOR$IOS_F6995. Z is not a standard edit descriptor in format. If you want to transfer hexadecimal values, you must use the edit descriptor form Z`w[.m]`, where `w` is the field width and `m` is the minimum number of digits that must be in the field (including leading zeros).
653	severe (653): DOS graphics not supported under Windows NT FOR$IOS_F6996.
654	severe (654): Graphics error FOR$IOS_F6997. An OPEN statement in which IOFOCUS was TRUE, either explicitly or by default, failed because the new window could not receive focus. The window handle may be invalid, or closed, or there may be a memory resource problem.
655	severe (655): Using QuickWin is illegal in console application FOR$IOS_F6998. A call to QuickWin from a console application was encountered during execution.
656	severe (656): Illegal 'ADVANCE' value FOR$IOS_F6999. The ADVANCE option can only take the values 'YES' and 'NO'. ADVANCE='YES' is the default. ADVANCE is a READ statement option.
657	severe (657): DIM argument to SIZE out of range FOR$IOS_F6702. The argument specified for DIM must be greater than or equal to 1, and less than or equal to the number of dimensions in the specified array. Consider the following: i = SIZE (array, DIM = dim) In this case, `1 <= dim <= n`, where `n` is the number of dimensions in array.
658	severe (658): Undefined POINTER used as argument to ASSOCIATED function FOR$IOS_F6703. A POINTER used as an argument to the ASSOCIATED function must be defined; that is, assigned to a target, allocated, or nullified.
659	severe (659): Reference to uninitialized POINTER FOR$IOS_F6704. Except in an assignment statement, a pointer must not be referenced until it has been initialized: assigned to a target, allocated or nullified.
660	severe (660): Reference to POINTER which is not associated FOR$IOS_F6705. Except in an assignment statement and certain procedure references, a pointer must not be referenced until it has been associated: either assigned to a target or allocated.
661	severe (661): Reference to uninitialized POINTER 'pointer' FOR$IOS_F6706. Except in an assignment statement, a pointer must not be referenced until it has been initialized: assigned to a target, allocated or nullified.
662	severe (662): reference to POINTER "pointer" which is not associated FOR$IOS_F6707. Except in an assignment statement and certain procedure references, a pointer must not be referenced until it has been associated: either assigned to a target or allocated.
663	severe (663): Out of range: substring starting position "pos" is less than 1 FOR$IOS_F6708. A substring starting position must be a positive integer variable or expression that indicates a position in the string: at least 1 and no greater than the length of the string.
664	severe (664): Out of range: substring ending position "pos" is greater than string length 'len' FOR$IOS_F6709. A substring ending position must be a positive integer variable or expression that indicates a position in the string: at least 1 and no greater than the length of the string.
665	severe (665): Subscript "number" of "string" (value "var") is out of range ('first:last') FOR$IOS_F6710. The subscript for a substring within a string is not a valid string position: at least 1 and no greater than the length of the string.
666	*severe (666): Subscript "number" of "string" (value "var") is out of range ('first:')** FOR$IOS_F6711. The subscript for a substring within a string is not a valid string position: at least 1 and no greater than the length of the string.
667	severe (667): VECTOR argument to PACK has incompatible character length FOR$IOS_F6712. The character length of elements in the VECTOR argument to PACK is not the same as the character length of elements in the array to be packed.
668	severe (668): VECTOR argument to PACK is too small FOR$IOS_F6713. The VECTOR argument to PACK must have at least as many elements as there are true elements in MASK (the array that controls packing).

Dynamic memory allocation is limited by several factors, including swap file size and memory requirements of other applications that are running. If you encounter an unexpectedly low limit, you may need to reset your virtual memory size through the Windows Control Panel or redefine the swap file size. Allocated arrays that are no longer needed should be deallocated.
719	severe (719): Attempt to DEALLOCATE part of a larger object FOR$IOS_F6764. An attempt was made to DEALLOCATE a pointer to an array subsection or an element within a derived type. The whole data object must be deallocated; parts cannot be deallocated.
720	severe (720): Pointer in DEALLOCATE is ASSOCIATED with an ALLOCATABLE array FOR$IOS_F6765. Deallocating a pointer associated with an allocatable target is illegal. Instead, deallocate the target the pointer points to, which frees memory and disassociates the pointer.
721	severe (721): Attempt to DEALLOCATE an object which was not allocated FOR$IOS_F6766. You cannot deallocate an array unless it has been previously allocated. You cannot deallocate a pointer whose target was not created by allocation. The intrinsic function ALLOCATED can be used to determine whether an allocatable array is currently allocated.
722	severe (722): Cannot ALLOCATE scalar POINTER -- out of memory FOR$IOS_F6767. There is not enough memory space to allocate the pointer. Dynamic memory allocation is limited by several factors, including swap file size and memory requirements of other applications that are running.

Allocated arrays that are no longer needed should be deallocated.
728	severe (728): Cannot allocate automatic object -- out of memory FOR$IOS_F6773. There is not enough memory space to hold the automatic data object. Dynamic memory allocation is limited by several factors, including swap file size and memory requirements of other applications that are running. If you encounter an unexpectedly low limit, you may need to reset your virtual memory size through the Windows* Control Panel or redefine the swap file size. Allocated arrays that are no longer needed should be deallocated. An automatic data object is an object that is declared in a procedure subprogram or interface, is not a dummy argument, and depends on a nonconstant expression. For example: SUBROUTINE EXAMPLE (N) DIMENSION A (N, 5), B(10*N) The arrays `A` and `B` in the example are automatic data objects.
729	severe (729): DEALLOCATE failure: ALLOCATABLE array is not ALLOCATED FOR$IOS_F6774. It is illegal to DEALLOCATE an array that is not allocated. You can check the allocation status of an array before deallocating with the ALLOCATED function.

745	severe (745): Out of range: UBOUND of assumed-size array with DIM==rank ("rank") FOR$IOS_F6790. The optional argument DIM specifies the dimension whose upper bound is to be returned. An assumed-size array is a dummy argument in a subroutine or function, and the upper bound of its last dimension is determined by the size of actual array passed to it. Assumed-size arrays have no determined shape, and you cannot use UBOUND to determine the extent of the last dimension. You can use UBOUND to determine the upper bound of one of the fixed dimensions, in which case you must pass the dimension number along with the array name.
746	severe (746): Out of range: DIM argument ("dim") to UBOUND greater than ARRAY rank FOR$IOS_F6791. The optional argument DIM specifies the dimension whose upper bound is to be returned, and must be greater than or equal to 1 and less than or equal to the number of dimensions (rank) in the array.
