The toggle wasn't waht I was looking for. I did try it. When you hold down the button and the toggle was going - on/off/on/off etc.....

Thanks for all the help. I am sure I will be posting more questions as I move forward.

Thanks again -

Hi Keith,
Looks like a classic IF THEN ELSE to me.

TRISB = %00001111    ' 4 upper as outputs 4 lower as inputs
IF  PortB.0 = 1 THEN ' if true then goto next statement
PortB.4 = 1          ' turn on this port 
ELSE                 ' goes to here if false
PortB.4 = 0          ' Turns this port off
ENDIF                ' ends the if then test for true / false and allows code to continue

make sure to use resistors pulling down if you close switches to activate or pulling up if you open switches to activate.

Not sure at all but...

        TRISB=%00001111
        PORTB=0

Loop:
        PORTB=(PORTB<<4)
        PAUSE 200
        GOTO Loop
