Need help with simple programming question

AiR_GuNNeR

I want to activate one of three lights and monitor one of three switches based on a random number. The light part is easy. I have
Light1 var 0
Light2 var 1
Light3 var 2
LightThatIs on var WORD

I set LightThatIson to one of the lights, then call
HIGH LightThatIsOn
to activate thelight, and also use that variable to shut it off as well. The problem is I also need to monitor one of three switches depending on which light is on.

If i have this:
Switch1 PIN 4
Switch2 PIN 5
Switch3 PIN 6
ActiveSwitch var WORD

ActiveSwitch = Switch1

DO
LOOP WHILE ActiveSwitch = 0

ActiveSwitch isn't actually tied to Switch1, or Pin 4. Can you somehow declare a varable and set it to an input pin number programatically, or do you need to use the BUTTON statement?
Thanks in Advanced

activeswitch VAR Byte

'Set activeswitch to one of the three below
activeswitch= %01000000 'for pin 6
activeswitch= %00100000 'for pin 5
activeswitch= %00010000 'for pin 4


' INL is pins 0 through 7 as one Byte (SEE MEMORY AND VARIABLES IN HELP)
' so IF all pins are ON it will = 255 = (%11111111)
' The & (bitwise AND) operator masks only the PIN you set in activeswitch
' If the bit is not a 1, the return of the operation is zero
DO
LOOP WHILE (INL & activeswitch) = 0
