Example — Starting a Program at a Specific Entry Point

To begin execution at an entry point other than the first, you can specify the alternate entry point or CSECT name on the START command. For example, if ODDJOB has several entry points and you want to start execution at the one named CLEANUP, enter
start cleanup
Or, you can start execution at a different entry point by specifying the entry point on the LOAD (or INCLUDE) command with the RESET option.
load oddjob (reset cleanup
start
