Thanks for the hints! But just to be clear, I'm not that good, and also if I could do it in my spare time it would go to sourceforge or some other type of free software place like CBT. I am NOT looking for a commercial product. Not at all. Just something to do that helps me learn and perhaps a hobby in my spare time. Like the CBT guys do. Nothing more. (-:
I use a lot of free MVS software like XMITIT and such, and I thought always a Rexx debugger ISPF-style would be cool. I'm not saying I can do it, maybe it is too over-my-head, but maybe not. I was only just asking.

I have not used XDC or CA-Xpediter, but I would imagine you could write a debugger in "mostly" Rexx with some assembler. Take a look at the TSO/E Programming Services manual for a discussion of how to write a native TSO full screen program. You will also have to give some thought to the "debugging services" you wish to provide: how you will implement breakpoints, stepping through instructions, and so forth. Also to the various storage and register displays, etc. If I were considering doing this as a commercial product, I would consider - the market for developer tools is always a difficult one - the market for z/OS developer tools is small and shrinking - CA-Xpediter kind of owns the big-deal corporate market space. CA is a tough incumbent to displace. - XDC is pretty established in the "word-of-mouth" market - There are other competitors as well. ASG has a debugger that competes with CA-Xpediter that they got from the Viasoft acquisition. Good luck!
