If the calling program has a dynamic storage area associated with
it, you can specify that CSRL16J free some or all of this storage
area before it transfers control to the target routine. In the L16J
parameter list, specify the following fields:
- L16JSUBPOOL
- Specify the subpool of the area that you want the system to
free.
- L16JLENGTHTOFREE
- Specify the length, in bytes, of the dynamic storage area you
want the system to free.
- L16JAREATOFREE
- Specify the address of the dynamic storage area you want the
system to free.
Make sure that the address is on a doubleword boundary.
Otherwise, the service ends with an abend code X'978'. See z/OS MVS System Codes for
information on abend code X'978'.
The system frees the storage only when the CSRL16J callable
service is successful.
