Arguments

size

Is the length of the statement field in a fixed-form source file. Possible values are: 72, 80, or 132.

Default

72

If you do not specify this option or you specify noextend-source, the statement field ends at column 72.

132

If you specify extend-source without size, the statement field ends at column 132.

Description

This option specifies the size (column number) of the statement field of a source line in a fixed-form source file. This option is valid only for fixed-form files; it is ignored for free-form files.

When size is specified, it is the last column parsed as part of the statement field. Any columns after that are treated as comments.

If you do not specify size, it is the same as specifying extend-source 132.
