Back to the beginning

This is an example that just does not work - OK laugh but once I get through the basics I'll be playing all night.

' Name : BLINKXU.pbp
' Compiler : PICBASIC PRO Compiler 2.6
' Assembler : MPASM
' Target PIC : PIC18F4550 or similar type
' Hardware : LAB-XUSB Experimenter Board
' Oscillator : 20MHz external
' Keywords : FOR NEXT
' Description : PICBASIC PRO program to blink an LED connected
' to PORTD.0 about once a second.
'

' Define LOADER_USED to allow use of the boot loader.
' This will not affect normal program operation.


' RESET_ORG can be set to move the BASIC program out of the way
' of any boot loader running from location 0, such as the
' Microchip USB boot loader
'Define RESET_ORG 800h

#config
_config _mclre_on & _CP_OFF & _WDT_OFF
#endconfig


mainloop:
high porta.1 ' Turn on LED connected to PORTD.0 <----- SYNTAX ERROR
Pause 500 ' Delay for .5 seconds
Low porta.0 ' Turn off LED connected to PORTD.0
Pause 500 ' Delay for .5 seconds
Goto mainloop ' Go back to loop and blink LED forever

End


Although the comments box states that it is for a PIC18F452 the selection box on the compiler is set to 12F509.

Even if the poor 12F509 does not have enough memory for the task in hand I shouldn't get syntax errors ?
