Providing an address space termination routine z/OS MVS Programming: Extended Addressability Guide SA23-1394-00 |
|
You can provide a routine that receives control when the address space terminates for reasons other than the ASDES macro. Specify the address of the routine on the TRMEXIT parameter. The termination routine receives control in 31-bit addressing mode, supervisor state, and in the same key as the program that issued the ASCRE macro. The routine is an asynchronous exit that resides in the creating program's address space and runs under its TCB. To identify the terminating address space to the termination routine and pass data, use the 64-bit area provided on the UTOKEN parameter. Specify the address of this data area on the UTOKEN parameter. The UTOKEN parameter provides a 64-bit area in which the creating program
can pass data to the termination routine. Use UTOKEN to:
On entry to the routine:
The termination routine will not get control for either of the
following two reasons:
