First Failure Data Capture Support

The INGHWCOM communications module supports the First Failure Data Capture debug aid, provided by NetView for high level language command processors, written in PL/I or C. In case of an INGHWCOM abnormal end, message CNM983E, CNM998E, or CNM999E is issued.

Message CNM983E contains the HLL API user trace information that is maintained by INGHWCOM. This information allows you to determine the internal program flow at error time. If available, save this debug aid information before contacting IBM® for service. For more information about the diagnostic messages, see IBM Z® NetView Messages and Codes.
