You've not heard of that?  Amazing.  You build it into your os9boot 
file, usually right after os9p3, which is right after os9p2, and then 
use it as a subroutine in your program.

os9p3 is an error interceptor, taking any error return and reading its 
description from defs/error.h or some such, thereby relieveing you 
from wearing out the manuals looking up the error codes.  It makes 
the manuals last a lot longer :-)

os9p4 is a register dumper, adding the call f$regdmp to the os.  Save 
the CC on the stack, call it from anyplace in your program and the 
registers will be dumped to stdout.

When it returns, pop the CC off the stack and continue on your merry 
way with nothing changed.  Its CC output is correct as printed to std 
out, but will not be correct by the time it returns, hence the pushs, 
pulls to save it for your program.  Its a great troubleshooter.
