Just a note about the 16 bit operations, they produce the correct 16 bit value, but the carry (ie set after addition result > 65,536) may not be correct. This is an issue in some applications; most typically, I see other add/subtract code snippets which keep the carry correct for noting that an out of bound condition exists - the problem is that they don't produce the correct 16 bit result. Hmmm... Maybe I should come up with a snippet that does both. Regarding the HP 16C calculator thread; I guess I'm a genius. When I was at school, I bought two of them (one for work, one for home). They are the best programmer's calculators any developed - I would be lost without mine. I just wish HP would come up with an updated version. Sorry, I've been away for a few days; if you've sent me a note and are looking for a reply, I'll get to it in the next few days.
