Thanks Henrik, so Say A=200 B=300, C in this case will be 65535-100=65435, right? So if I take 65535 and minus it result, I should receive correct difference between A and B, right?
Oh and by the way, currently I don't have access to machine with PBP, what will happen if C=A-B and B is > A ? all variables are word length. I need to determine difference between A and B, but...
In my case, there will be 16F886 running at 8mhz and maximum frequency will be around 2khz, so I guess, modulo variant will also work. Will assemble test circuit...
Wasn’t it just something like this?
not even timing of course because every fifth iteration takes slightly longer to execute, but could be balanced up if it mattered.

Re: Doing something at predefined amount of steps?
No, 200-300=65436.
HenrikOlsson Yesterday, 23:0165435 is -101 in two's complement because 65435+101 = 65536 which, when being truncated to 16 bits is 0.
If what you want is the difference between the two numbers while not...
