 		 #166159 - I have seen ...
Responding to: ???'s previous message
.. the compiler flipping (for no appearent reason) between something like this
DEC count?041+01H
JNZ ?C0001

and something like this
DJNZ count?041+01H,?C0001

which, by the C standard is perfectly legal

If I recall correctly, when I stumbled over this one, the cause (as perceived by me) was adding a variable somewhere else. I did not investigare a lot because I would never depend on the compiler not doing what by the C standard is perfectly legal.
