To test your user exit using the API_com_test configuration parameter:

  1. Set the value of the API_com_test configuration parameter to Y or O so that you can receive output to troubleshoot your user exit, if necessary.

  2. View the contents of the APICOM and UELECMD files to examine the LE Command structure before and after invoking the user exit.

See Appendix A, “LTM for MVS Configuration Parameters,” for more information about the LTL_test_only and API_com_test configuration parameters.
