The TSO/E message issuer routine issues a message using PUTLINE, PUTGET, write-to-operator (WTO), or write-to-programmer (WTP). You can indicate to IKJEFF02 which of these services should be used to issue the message, or you can allow the default, PUTGET, to be used. For prompting and mode messages, you should indicate to IKJEFF02 that PUTGET should be used to issue the message; for informational messages, PUTLINE should be used. If you want to issue the message in the language specified in the user profile table (UPT), you must indicate to IKJEFF02 that PUTGET or PUTLINE should be used.

For more information about providing translated messages, see PUTLINE Message Line Processing.

You can invoke IKJEFF02 just to issue the message to the terminal, both to issue the message and return the requested message to the caller in the caller's buffers, or just to return the message to the caller. This process of returning the message is referred to as extracting the message.

The TSO/E message issuer routine simplifies the issuing of messages with inserts because hexadecimal inserts can be converted to printable characters and the same parameter list can be used to issue any message. It also makes it more convenient to place all messages for a command in a single CSECT or assembly module, which is important when message texts must be modified. Adding or updating a message is simpler when IKJEFF02 is used, rather than PUTLINE or PUTGET.
