Step 3. Code Your Exit Routines

In order to code your exit routines you will have to refer to:

• User Exit Routine Reference to find out exactly when each routine receives control, what the register conventions are, and so forth
• Mapping Macro Reference to find out the formats of mapping macros that you will use in your routines
• Executable Macro Reference to find out the formats of executable macros that you will use in your routines.
