PAUSE
Statement: Temporarily suspends program execution and lets you execute operating system commands during the suspension. The PAUSE statement is a deleted feature in the Fortran Standard. Intel® Fortran fully supports features deleted in the Fortran Standard.
PAUSE [pause-code]
pause-code |
(Optional) Is an optional message. It can be either of the following:
|
If you specify pause-code, the PAUSE statement displays the specified message and then displays the default prompt.
If you do not specify pause-code, the system displays the following default message:
FORTRAN PAUSE
The following prompt is then displayed:
On Windows* systems:
Fortran Pause - Enter command<CR> or <CR> to continue.
On Linux* and macOS systems:
PAUSE prompt>
For alternate methods of pausing while reading from and writing to a device, see READ and WRITE.
Effect on Windows* Systems
The program waits for input on stdin. If you enter a blank line, execution resumes at the next executable statement.
Anything else is treated as a DOS command and is executed by a system( ) call. The program loops, letting you execute multiple DOS commands, until a blank line is entered. Execution then resumes at the next executable statement.
Effect on Linux* and macOS Systems
The effect of PAUSE differs depending on whether the program is a foreground or background process, as follows:
If a program is a foreground process, the program is suspended until you enter the CONTINUE command. Execution then resumes at the next executable statement.
Any other command terminates execution.
If a program is a background process, the behavior depends on stdin, as follows:
If stdinis redirected from a file, the system displays the following (after the pause code and prompt):
To continue from background, execute 'kill -15 n'
In this message, nis the process id of the program.
If stdinis not redirected from a file, the program becomes a suspended background job, and you must specify fgto bring the job into the foreground. You can then enter a command to resume or terminate processing.
Example
The following examples show valid PAUSE statements:
PAUSE 701
PAUSE 'ERRONEOUS RESULT DETECTED'
The following shows another example:
CHARACTER*24 filename
PAUSE 'Enter DIR to see available files or press RETURN' &
&' if you already know filename.'
READ(*,'(A\)') filename
OPEN(1, FILE=filename)
