A period (.) followed by up to three characters giving the filename extension. You can specify an extension of spaces by putting just the period. If you omit the whole extension, the system supplies one of the following extensions:
.cbl | For a source code file |
.obj | For the output object code file |
.lst | For the output COBOL source listing |
.grp | For the output object code listing |
.int | For the output intermediate code file |
.gnt | For the output generated code file |
Note: You can use the OSEXT Compiler directive to change the default extension for a source code file to something other than .cbl.
