I think I'm in way over my head understanding any of the asr.h or asr.c 
files. My C/C++ knowledge is extremely limited, at best.

As far as a HEX editor goes on the disk; I'm at a lost as to where to 
point it (see above.)

If there's any way in which you can describe the methods for pulling out 
some debug data to submit, I'd be grateful.

Once again, thanks.
