Explanation

An abend occurred during a subsystem interface (SSI) request to the JES2 subsystem.

The task attempts recovery. If the task cannot percolate the error, the task returns to the SSI caller with a return code of 16 in register 15. The SSI caller assumes that the JES2 subsystem did not satisfy the SSI request.

The dump is written for the address space that issued the SSI request. The areas dumped are ALLPSA, CSA, LPA, LSQA, and RGN. The component section of the dump contains:

The name of the SSI routine that abended
The associated JES2 module name
The offset of the failing instruction into the JES2 module
