with me so far?

Yes. I have a Nespresso and I'm not affraid to use it.

attached is

Is it?

OK, I'll get serious now.

Use a shadow word variable to keep the state of each button. Then XOR the read state with that shadow.

symbol Lights = w1
symbol Buttons = w0

init:
   Lights = 0  ' all lights off

main:
   ' ...
   ' Read buttons
   ' ...
   [B]Lights = Lights XOR Buttons[/B]
   ' Output Lights
   goto main

Your what you have so far attachment appears to be missing

Try running this code through the simulator, it simulates the SetLed code ( input buttons in w0, leds lit in w3 ) and you can only control 8 input buttons, but it should give the general idea -

#Picaxe 20M

Do
  w0 = pins
  Gosub SetLeds
  pins = w3
Loop

SetLeds:
  w2 = w0 ^ w1 & w0
  w1 = w0
  w3 = w3 ^ w2
  Return

Poor manners

@QuIck,

It is bad form to remove the original question!
This does not help anybody at all. If you have found the answer, please be kind enough to actually show it. I am sure that others would have had a similar question and benefitted from the answer.
