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!

Subject: How to write a full-screen Rexx debugger?

Does anyone know how one might write a full-screen Rexx debugger, like z/XDC
or Xpediter?  I've spent a couple of evenings digging through the Rexx
Reference, but so far I've not stumbled on a way to do it.  Or even if it
can be done.
