Example: Deleting old spooled files

The following application program runs using the Delete Old Spooled Files (DLTOLDSPLF) command.

This example has three major parts:

  1. The DLTOLDSPLF command calls the delete old spooled files (DLTOLDSPLF) program in one of the following languages:
    • OPM RPG
    • OPM COBOL
    • ILE C
  2. The DLTOLDSPLF program is supplied in OPM RPG, OPM COBOL, and ILE C. It does the following:
    1. Creates a user space (QUSCRTUS API).
    2. Generates a list of spooled files (QUSLSPL API).
    3. Retrieves information from a user space using one of the following:
      • QUSRTVUS API
      • QUSPTRUS API
    4. Retrieves more spooled file attribute information received from the user space (QUSRSPLA API).
    5. Calls the CLDLT program to delete the spooled files.
    6. Sends a message to the user (QMHSNDM API).
    7. Deletes the user space (QUSDLTUS API).
  3. The CL delete (CLDLT) program does the following:
    1. Deletes the specified spooled files (DLTSPLF command).
    2. Sends a message if the spooled file was deleted (SNDPGMMSG command).

CL Delete (CLDLT) program

The DLTOLDSPLF program, written in OPM RPG, OPM COBOL, or ILE C, calls a CL program named CLDLT. The CLDLT program deletes the spooled files and the user space. The following is the CL source for the CLDLT program.
