Using the TSO/E Message Issuer Routine (IKJEFF02)

If your command processor issues messages with numerous inserts, you should use the TSO/E message issuer service routine (IKJEFF02) instead of PUTLINE and PUTGET. Using IKJEFF02 has several advantages:

It simplifies the issuing of messages with inserts because the same parameter list can be used to issue any message.
This service makes it convenient to place all messages for a command in a single CSECT. This is important when you have to modify message texts.
It provides support for second-level messages that are associated with informational or prompting messages.

IKJEFF02 also provides support for displaying messages in the user's desired language as specified in the user profile table. The MVS™ message service must be active to use this support. In addition, a translated version of the message in the specified language must exist.
