Preparing an IMS program

To prepare an IMS program, do the following tasks:

1. Verify that Planning your debug session and Updating your processes so you can debug programs with z/OS Debugger have been completed.
2. Contact your system programmer to find out the preferred method for starting z/OS® Debugger and which of the following methods you need to use to specify TEST runtime options:
   • Specifying the TEST runtime options in a data set, which is then extracted by a customized version of the Language Environment® user exit routine CEEBXITA. See Specifying the TEST runtime options through the Language Environment user exit for instructions.
   • Specifying the TEST runtime options in a CEEUOPT (application level, which you link-edit to your application program) or CEEROPT module, (region level). See Starting z/OS Debugger under IMS by using CEEUOPT or CEEROPT for instructions.
   • Specifying the TEST runtime options through the EQASET transaction for non-Language Environment assembler programs running in IMS TM. See Running the EQASET transaction for non-Language Environment IMS MPPs for instructions.
   • Managing runtime options for IMSplex users by using IBM z/OS Debugger Utilities.
3. To debug COBOL programs, include the IMS interface module DFSLI000 from the IMS RESLIB library.
