UTM messages to MSGTAC

MSGTAC is a special asynchronous program unit, that users can program themselves, (see the openUTM manual „Programming Applications with KDCS”).

If there is an MSGTAC program, and a message occurs for which MSGTAC was defined as the message destination, the asynchronous service MSGTAC is started. The MSGTAC program can read a number of messages in a single program unit run.

The MSGTAC program unit runs under the internal UTM user ID KDCMSGUS with KSET=MASTER and PERMIT=ADMIN. It must be defined in a TAC statement with TAC KDCMSGTC,PROGRAM=... .
