The /OUTBIT declaration gives the name LED1 to port B bit 0, and defines a
>bunch of MPASM macros and string substitutions accordingly.  The "n" in the
>declaration indicates negative logic, meaning the "ON" case is logic low

>"OFF" is logic high (LED connected with series resistor to Vdd for

>SET_LED1_ON and SET_LED1_OFF are MPASM macros defined in the expansion of
>/OUTBIT.  These set the bank as appropriate (using my DBANKIF macro, of
>course) and then set the pin high or low according to the desired on or off
>state.  On PICs with LAT registers, SET_LED1_ON and SET_LED1_OFF will write

Oww, I do like that enhancement to the macros. Thanks Olin.

Haven't gone investigating yet, but is there a similar way of setting up the 
input sense on the /INBIT macro, and testing if off or on?
