I did develop a fully featured debugger solely on TRAP for VSE.
I did that in 2000 as proof of concept or better to show that TRAP is not there for "year 200o fix up" as pops did say at that time.
Originally it was object code only in CICS (just to see that it works)- meanwhile I support CICS and batch as well as debugging source code.
I am semi retired now- but the tool is still available for free for a VSE environment. It supports z-arch including the z14. Because of the only use of TRAP to intercept it doe not need to know every instruction.
What I like to say: pops has everything needed, but a software supported API would be great.
I know of one big z/OS installation that has a debugger in use that uses TRAP (and the author is on IBM-main as well)
Mentioning software vendors- there is a debugger called z/TDF from Arney Software - runs on z/OS and explored TRAP as well.
Chuck is a good friend and I can see/imagine roots of his debugger in talks we had (and it is way younger than mine)MINE) during various real life meeting (in bars) we had.
