Need 4 modes with just 3 switches - need all modes to be selectable QUICKLY!

[HankMcSpank]

so wouldn't SOMETHING as noobesque (as befits me) like this suffice...

Switch_Interrupt:

If sw1 = 0 then 
mode = 1
HIGH LED1  'green LED
LOW LED2   ' red LED
endif

If sw2 = 0 then 
mode = 2
HIGH LED1  'green LED
HIGH LED2   ' red LED
endif

If sw3 = 0 then 
mode = 3
LOW  LED1  'green LED
HIGH LED2   ' red LED
endif

@ INT_RETURN

(Yielding either a green LED, amber-esque led, red led)

ok, it needs padding out....just wanted to get the main cut & thrust across.... the LED would change colour pretty darned quick, thereby giving the user the feeling of 'rapido'.

Yes, sure there'll be an interupt generated when the finger is removed from the switch, but since none of the conditions in the Switch_interrupt subroutine would be met (since the pins would be high when the second interrupt happens) nothing will happen? - a few clock cycles wasted - but hey, there's heaps more where they came from?

or would the quick succession interrupt from the finger being removed from the switch cause probs?
