CSFE—terminal and system test
Global trap/trace program exit and global
kernel exit
You can use CSFE DEBUG with the TRAP or GTRAP
operand to activate and deactivate the global trap/trace
program exit routine or the global kernel exit routine
respectively.
These exits are intended to be used only under the guidance
of IBM support personnel.

TRAP={ON|OFF}
The global trap/trace program exit routine is to be
activated or deactivated.
GTRAP={ON|OFF}
The global kernel exit routine is to be activated or
deactivated. On each domain call and return, and each
subroutine call and return, the kernel invokes the global
kernel exit routine, if it is activated.
TRAP= ON or off
specifies that the global/trap exit routine is to be
activated or deactivated.
