It doesn't work, only appears to work in you case.  The ",0" causes the
result of the INCF to be written to W, which is why W gets modified.  If W
contains whatever FSR happens to be pointing to, then it will appear to
increment.  If you look into this more carefully you will see that it
doesn't work.  Of course you're messing with some third party emulator, so
who knows what you will see.  Try it with real MPLAB if you continue to have
a problem.
