This exit gets control when conversion processing occurs in the JES2 address space. It allows you to provide an exit routine for scanning resolved Converter/Interpreter (C/I) text. If this exit is implemented and enabled, it is taken after the converter has converted each JCL statement into C/I text and once after all of the JCL for a particular job has been converted to C/I text. If you are running conversion in the JES2CI address space (because JOBDEF INTERPRET=JES is set), then exit 60 is taken at the same point in processing as this exit.

After the converter has processed the entire job, this exit again allows you to direct JES2 either to cancel the job or to allow it to continue with normal execution.

C/I text is represented by ‘keys’ that identify the various JCL parameters. These keys are documented in the JES2 assembly, HASPDOC, which calls macros IEFVKEYS and IEFTXTFT, which are distributed in SYS1.MODGEN. Specifying KEYS on $MODULE causes IEFVKEYS to be expanded; specifying TEXT on $MODULE causes IEFTXTFT to be expanded. IEFVKEYS contains the definition of the values for each key, and IEFTXTFT contains the definition of the format of the Converter/Interpreter text. For more information about C/I text, see z/OS MVS Installation Exits.
