' Define LOADER_USED to allow use of the boot loader.
' This will not affect normal program operation.
Define LOADER_USED 1

i    Var Byte   ' Define loop variable
LEDS Var PORTB  ' Alias PORTB to LEDS

   TRISB = %00000000  ' Set PORTB to all output

mainloop:
   LEDS = 1           ' First LED on
   Pause 500          ' Delay for .5 seconds

   For i = 1 To 2     ' Go through For..Next loop 2 times
     LEDS = LEDS << 1 ' Shift on LED one to left
     Pause 500        ' Delay for .5 seconds
   Next i
   Goto mainloop      ' Go back to mainloop and blink LED forever
