Use the ASDES macro to delete an address space that was created through the ASCRE macro. The STOKEN parameter is required on the ASDES macro. You can obtain this value from the data output field located at the address specified on the ODA parameter. The macro IHAASEO maps the 24-byte data area specified by ODA. For the format of IHAASEO, see the ASEO data area in See z/OS MVS™ Data Areas in the z/OS® Internet Library: &zosliburl;.

Note that the termination routine that was optionally specified on the TRMEXIT parameter on the ASCRE macro does not get control in this case.

The ASDES process is similar to what CALLRTM TYPE=MEMTERM provides. Be aware that tasks in the abending address space cannot perform recovery and task-level resource managers cannot get control; address space recovery routines and resource managers can get control. Instead of using ASDES, you might use CALLRTM TYPE=ABTERM,RETRY=NO to abend each job step task in the address space. When all tasks in the address space have terminated, the system deletes the address space.
