The following application program runs using the Delete Old Spooled Files (DLTOLDSPLF) command. This example has three major parts:
The DLTOLDSPLF command calls the delete old spooled files (DLTOLDSPLF) program in one of the following languages:
OPM RPG
OPM COBOL
ILE C
The DLTOLDSPLF program is supplied in OPM RPG, OPM COBOL, and ILE C. It does the following:
Creates a user space (QUSCRTUS API).
Generates a list of spooled files (QUSLSPL API).
Retrieves information from a user space using one of the following:
QUSRTVUS API
QUSPTRUS API
Retrieves more spooled file attribute information received from the user space (QUSRSPLA API).
Calls the CLDLT program to delete the spooled files.
Sends a message to the user (QMHSNDM API).
Deletes the user space (QUSDLTUS API).
The CL delete (CLDLT) program does the following:
Deletes the specified spooled files (DLTSPLF command).
Sends a message if the spooled file was deleted (SNDPGMMSG command).
DLTOLDSPLF Command Source
The command source for the DLTOLDSPLF command follows:

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.
