How Messages Are Captured

TSO command processor messages may be captured using one of the following methods:

• In CLISTs, messages may be captured by setting the SYSOUTTRAP CLIST variable. For more information regarding the trapping of command processor output, consult the IBM manual entitled z/OS V1R8.0 TSO/E CLISTs, SA22-7781-04.
• In TSO/E REXX, messages may be captured by using the OUTTRAP function. For more information regarding the trapping of command processor output, consult the IBM manual entitled z/OS V1R8.0 TSO/E REXX Reference, SA22-7790-07.
• In OPS/REXX programs, you can use the external data queue to trap TSO command output from commands run under the ADDRESS TSO host command environment.

Note: In OPS/REXX programs, it is generally easier and more efficient in CPU overhead to use an OPS/REXX function or host command environment instead of a TSO command processor.
