Messages are sent to several transient data destinations, for example:
For a list of the destinations used by CICS®, see the CICS System Definition Guide. Use a copy of the appropriate messages and codes documentation to look up any messages whose meaning you do not know. All CICS messages and codes are documented in CICS Messages and Codes, and are available in the CICS Information Center. Make sure that you also have some documentation of application messages and codes for programs that were written at your installation.
