The easiest way would be to use the TOGGLE command.

start:
if (your input pin) = 0 then toggle (your led port) : pause 50 : goto start
goto start

Please don't post the same question in multiple locations. Pretty much everybody reads all the forums here, and it's helpful to keep all the responses together. Welcome aboard!
