    Hi Peter,

    Those are "PIN Numbers".
    Their location is specified by PORTL and PORTH.

    Post PicBasic Pro Compiler manual

    Quote Originally Posted by PicBasic Pro Compiler manual
    For compatibility with the BASIC Stamp, pins used in PicBasic Pro Compiler commands may also be referred to by a number, 0 - 15. This number references different physical pins on the PICmicro MCU hardware ports dependent on how many pins the microcontroller has.

    If a port does not have 8 pins, such as PORTA, only the pin numbers that exist may be used, i.e. 8 - 12. Using pin numbers 13 - 15 will have no discernable effect.

    This pin number, 0 - 15, has nothing to do with the physical pin number of a PICmicro MCU. Depending on the particular PICmicro MCU, pin number 0 could be physical pin 6, 21 or 33, but in each case it maps to PORTB.0 (or GPIO.0 for 8-pin devices, or PORTC.0 for a PIC14000).

    Hmmmm..
    Yeah, I thought it was probably sumpthin' like that. Is there any documentation around for the pin numbering as mentioned and as to what port lines they refer to on different PICs??
