PRIMARY INPUT FILE NAME EXTENSION

Syntax:

PRIMARY INPUT { FILE [NAME] | FILENAME } EXTENSION [:] <string>

Function:

Specifies the default input file name extension for primary Fortran files. In this context, a primary file is any Fortran source file which is not referenced in an INCLUDE statement.

The file name extension is written as a delimited or undelimited string, with or without a leading . (period) character.

This command is position sensitive in the command line or FSP file. It applies to all file names which follow it, and the default may be changed within a list of files.

If a sub-program input file has an extension which differs from the default, note that the extension is appended to the base file name with a separating underscore character. For example, if the default input file name extension is .for and a primary file is read with the name stats.bda, the corresponding output file name will be stats_bda.fpt. This behaviour is modified by the command KEEP FILE NAME EXTENSIONS.
