Hi all,

I'm very new to the PIC world and have a question about using MPLAB 5.7:

I wrote a simple program to set  Port Pin 0 in GPIO high on a PIC12C672
(to light up an LED).  When I run it through the MPLAM simulator and
step through, I notice that the GPIO register will not change (as seen
through the Special Function Register Window) no matter how I set those
bits ("BSF GPIO, 0" or "MOVWF GPIO").

I also have the same problem when I try to alter the bits in the
OPTION_REG on a PIC16F84.  I noticed that using the old OPTION command
will alter the bits, but MOVWF OPTION_REG (with the desired bits in the
W register) will not.

Can anyone shed some light on what I'm doing wrong?  Thanks in advance.

- James
