The steps to creating an exit program are
Create you exit program
Use WRKREGINF to work with exit programs
Use option 1 to add the program to the list of registered exit programs
This link to an example:

Examples: Create exit programs with RPG
The following example illustrates how to set up a user exit program with RPG*.
Note: Read the Code example disclaimer for important legal information.
**
** OS/400 SERVERS - SAMPLE USER EXIT PROGRAM
**
** THE FOLLOWING RPG PROGRAM UNCONDITIONALLY
** ACCEPTS ALL REQUESTS. IT CAN BE USED AS A SHELL
** FOR SPECIFIC APPLICATIONS. NOTE: REMOVE THE
** SUBROUTINES AND CASE STATEMENT ENTRIES FOR THE SERVERS
** THAT DO NOT REQUIRE
** SPECIFIC EXIT PROGRAM HANDLING FOR BETTER PERFORMANCE.
