I just got back from being out of town (and that's why I didn't respond to the
private message you sent). The bug you describe doesn't happen on my machine. So
the obvious question is: Are you using stimuli? You sen't the source file, but
you didn't send the start up script. If there are any stimuli attached to the
pins, then they could (and should) change states of the neighboring bits in a
bsf instruction. Try it with a real pic :). Of course, with a real pic you won't
notice the changes until you actually read the I/O port...
