Well, it's refreshing to learn something new. Anyway, here's the code that didn't come through earlier.

Code:
;This program will blink a light on portb.1 at a 1 hz rate   --
'with another LED on portd.1 blinking at a different rate
'different TMR1 preloads to get desired frequencies

wsave   VAR BYTE    $70     SYSTEM    ' alternate save location for W 
                                      ' if using $70, comment wsave1-3

wsave1  VAR BYTE    $A0     SYSTEM    ' location for W if in bank1
wsave2  VAR BYTE    $120    SYSTEM    ' location for W if in bank2
wsave3  VAR BYTE    $1A0    SYSTEM    ' location for W if in bank3

LED1   VAR  PORTB.1
led2   VAR portd.0
