TRAPLIST subcommand — list the status of IPCS traps

Use the TRAPLIST subcommand to display the status of IPCS-supplied traps.

If you write your own installation exit and use one of the exit service routines, which are described in z/OS MVS IPCS Customization, use the TRAPON, TRAPOFF, and TRAPLIST subcommands to obtain diagnostic input and output information. You can also use these subcommands to set traps when executing IPCS code that uses the exit service routines.
