Use SET CPCHECKING to activate or deactivate CP internal checking.
ON
ABEND
VMSTOP
indicates that internal CP checking should be activated. The action to be taken
when an untrue assertion is encountered is controlled by the subsequent
parameters.
ABEND
indicates that an abend should occur. Whether it is a hard abend or a soft
abend is controlled by the specific assertion case. It is typically a hard abend.
This is the default when CP internal checking is activated.
VMSTOP
this parameter is permitted only when CP is itself running in a virtual machine,
and is generally useful only for debugging CP. Specifying this parameter causes
CP to issue a DIAGNOSE X'08' instruction when an untrue assertion is
encountered, specifying a command string length of zero. This causes the
virtual machine to stop and for CP to post a read to the console. Messages are
sent to the console (from a DIAGNOSE X'08' MESSAGE * command) providing
information about the cause of the stop.
OFF
Indicates that CP internal checking should be deactivated.
HCP1007E The VMSTOP option is only permitted
when CP itself is running in a virtual
machine.
HCP6010I The CPCHECKING setting has been
changed to OFF to avoid a possible
abend loop. It may be set ON again if
desired.
