Why Define a User Exit?

The default migration ID determination exit should normally be adequate. However, uses for a user exit include:

• Handling in-house subsystems that do not use a command recognition character (that can be set in the CONSOLES parameter group). This can involve parsing the command text.
• The migration ID determination exit sets the MIGID for unrecognized commands to YES. However, if the subsystem can handle named consoles, then the user exit can set NO for these subsystem commands.
• Overriding the standard settings for some z/OS commands.
