/MAPPING_FILE[=filename]
       /NOMAPPING_FILE

    This qualifier instructs TEST/REWRITE to use the specified
    mapping file rather than the default mapping file named by the
    PMDF_MAPPING_FILE logical name, usually PMDF_TABLE:MAPPINGS.

    This qualifier has no effect unless /NOIMAGE_FILE was specified
    or no compiled configuration exists; use of any compiled
    configuration will preclude reading the mapping file.

    Use of the /NOMAPPING_FILE qualifier will prevent the PMDF_
    MAPPING_FILE file from being read in when there is no compiled
    configuration.
