For os9/nitros9 assembly work, there is an optional call, F$RegDump, that 
can be inserted in your code, wrapped in a store of CC on the stack, and 
a pull of CC afterwards, that will spit out the cpu's registers, all of 
them, when its encountered in your code.  I have made heavy use of it in 
the past to help  generate some of the bulletproof code I have done.  
Both vfy and myram benefitted greatly from its use.

My one regret is that I was never able to make an assembler directive equ 
that caused it to just disappear from finished code, I always had to 
edit it out by hand.
