I am starting with PICs and doing some simple programs with a PICKIT1 system. I had a problem where I want to use the pushbutton on the PICKIT, but it is tied to the MCLR line so it causes the micro to reset whenever the button is pressed. So I consulted the internet and this forum and I found a fix that works but only with PBP's internal assembler.
What am I doing wrong that MPASM doesn't like the directive?
