Debugging and testing

When an exit routine is called, bit 2⁴ of byte ESTKIND is set in the process control block (PCB):

ESTKEXIT EQU X'10'

At the end of the exit routine the bit is reset. The names used in the PCB can be generated via the DSTK macro.

Exit routines can be debugged with the products DAMP, HELGA and IDIAS. DAMP is described in the “Diagnostics Handbook” [3]. HELGA and IDIAS are internal diagnostic tools for the service technician.

The settings of AUDIT indicators are not changed by calling an exit routine.

Exit routines are treated as system components when taking dumps; no special measures are performed.
