Passing Control

When the IPCS user enters a CTRACE subcommand with the USEREXIT parameter, CTRACE calls, in this order:

Any component-supplied CTRF exit routines, as defined through the FILTERNAME parameter on the ITTFMTB macro
Any CTRF exit routines, as specified through the USEREXIT parameter on the CTRACE subcommand.

CTRACE calls the exit routines for each CTE that passes the standard filtering options in effect.

IPCS calls the CTRF exit routine one additional time, with the bit CTXIDONE in the CTXI turned on, after all CTEs are processed. This last call will not occur if either exit routine returns code 16, or if the exit routine returns code 12.
