Several UDCs are provided to simplify the use of the enhanced and new MPE/iX commands.
Several of the system-provided UDCs tailor the use of the LISTFILE command within the hierarchical file system. For example, a PLISTF UDC calls the LISTFILE command because the LISTF command does not list directories or files whose names are not consistent with the MPE syntax.
An additional UDC (DISCUSE) provides an alternate spelling of the DISKUSE command.

Check with your system manager to determine whether or not these UDCs are activated on your system.
