Syntax

MFILE | NOMFILE

MFILE: routes output produced by the MPRINT option to an external file. This is useful for debugging.
NOMFILE: does not route MPRINT output to an external file.

Details

The MPRINT option must also be in effect to use MFILE, and an external file must be assigned the fileref MPRINT. Macro-generated code that is displayed by the MPRINT option in the SAS log during macro execution is written to the external file referenced by the fileref MPRINT.

If MPRINT is not assigned as a fileref or if the file cannot be accessed, warnings are written to the SAS log and MFILE is set to off. To use the feature again, you must specify MFILE again and assign the fileref MPRINT to a file that can be accessed.
