Is there a COBOL debugger for IBM S/36 programs?

S/36 programs on an AS/400 (i5) can't be debugged using the system-supplied debuggers.

Converting the thousands of programs to ILE COBOL will be a multi-year project, and in the meantime, a third-party debugger is needed.

Thanks.

It's hard to imagine many 3rd-party developers devoting the time necessary to create a S/36 COBOL debugger that would run on an AS/400 series system. The development cost could be extraordinary, and the market would have been miniscule even 20 years ago when it would be at its highest demand. I can't say that none exist. It just seems unlikely.

While converting "thousands of programs to ILE COBOL" could indeed be a long process, there should only be a need to debug one or two at a time. Therefore it should only be one or two that needed to be converted at a time. (And certainly no new ones should be created for an S/36 environment.)

Also, no modifications should ever be made to a S/36-environment program. Those should always be converted first. There shouldn't be much need for debugging unchanged programs that have been running for 20 years or more.

The only direction might unfortunately be a phased, controlled conversion. I'd certainly embrace that direction.
