I don't know if compiled REXX works differently from interpretive.

There is a possibility that you are executing an ISPF service or
something that isn't interruptible.

I know that I might have to hit ATTN a few times and enter the HI
command to break a looping or long running REXX.

Can you execute with TRACE? Is there a call to a REXX external routine
that you can substitute your own code and use it to stop your REXX?
