The Application Message Facility contains:
GENCAT.PUB.SYS utility program
GENCAT Utility |
 |
GENCAT is a menu-driven program that performs various operations on message catalogs. It formats the message catalog for more efficient access, allows you to easily make changes to the catalog, and expands a formatted catalog to its original form. GENCAT can be run interactively or by a job.
Catalog Intrinsics |
|
Three intrinsics are available for accessing application message catalogs: CATOPEN, CATREAD, and CATCLOSE. These intrinsics open the formatted catalog, read and output the messages, and close the catalog. Use of these intrinsics is discussed in Chapter 3.
User Message Catalogs |
|
You create your own catalogs by organizing your numbered messages into numbered sets and then formatting them with GENCAT. Your messages may contain place holders so that at run time, parameters are substituted in the messages. Messages usually consist of error messages, prompts, and informational messages.
Creating, accessing, and modifying application message catalogs is discussed in Chapters 2-4.
