PROGRAM TERMINATED IN AN ERROR STATE. (CIERR 976)
:
If the SETDUMP command (or intrinsic) is invoked before running this program, a full dual
stack trace and a register dump is produced when the process aborts. Consider the
following example:
:setdump
:run nmbomb
**** Integer divide by zero (TRAPS 30)
ABORT: NMBOMB.DEMO.TELESUP

**** PROCESS ABORT INTERACTIVE DEBUG FACILITY ****
$2 ($22) nmdebug >
Note that in the above example, the user is left in Debug. At this point, the user is able to
enter any Debug command. The process may even be resumed (see theCONTINUE command
in chapter 4).
It is possible to specify what action should be taken when a process aborts by providing a
list of commands for Debug to execute. In the following example, a simple message is
printed if the process aborts.
:setdump ;debug="wl 'Oh my, our process is aborting !'"
:run cmbomb
**** PROGRAM ERROR #4 :INTEGER DIVIDE BY ZERO
ABORT: CMBOMB.DEMO.TELESUP
**** PROCESS ABORT STACKDUMP FACILITY ****
Oh my, our process is aborting !
