PROGCHK (CMS only)

Simulates a program check to the target program, typically to test the target program's recovery from program checks (for example, through an established ESPIE or ESTAE or ABNEXIT or PSW steal).

check-code

The program check code to be simulated. An integer, with the following possible values:

1: Operation exception
2: Privileged operation exception
3: Execute exception
4: Protection exception
5: Addressing exception
6: Specification Exception
7: Data exception
8: Fixed-point overflow exception
9: Fixed-point divide exception
10: Decimal overflow exception
11: Decimal divide exception
12: Exponent overflow exception
13: Exponent underflow exception
14: Significance exception
15: Floating-point divide exception

The program check is simulated with the current GPRs, FPRs, ARs, CREGS, and PSW.

As this command is intended to simulate an error and drive an error handler, that handler may be expecting some other conditions that must be set up before this command is issued. If necessary, you must first change these values before issuing the PROGCK command.
