O Editing
The O data edit descriptor transfers octal (base 8) values. It takes the following form:
Ow[.m]
The value of m (the minimum number of digits in the constant) must not exceed the value of w (the field width), unless w is zero. The m has no effect on input, only output.
The specified I/O list item can be of type integer, real, or logical.
Rules for Input Processing
On input, the O data edit descriptor transfers w characters from an external field and assigns their octal value to the corresponding I/O list item. The external field must contain only octal digits (0 through 7) or blanks. w must not be zero.
If the value exceeds the range of the corresponding input list item, an error occurs.
The following shows input using the O edit descriptor (the symbol ^ represents a nonprinting blank character):
Format Input Value O5 77777 32767 O4 77777 4095 O3 97^ An error; the 9 is invalid in octal notation
Rules for Output Processing
On output, the O data edit descriptor transfers the octal value of the corresponding I/O list item, right-justified, to an external field that is w characters long.
The field consists of zero or more blanks, followed by an unsigned integer constant (consisting of octal digits) with no leading zeros. A negative value is transferred in internal form without a leading minus sign.
If w is zero, the external field has the minimum number of characters necessary to represent the value. If both w and m are zero and the internal value is zero, the external field is one blank.
If m is specified, the unsigned integer constant must have at least m digits. If necessary, it is padded with leading zeros.
If m is zero, and the output list item has the value zero, the external field is filled with blanks.
The following shows output using the O edit descriptor (the symbol ^ represents a nonprinting blank character):
