Relay sequencer help

Hi again, guys,
here is a simple code that stamper Mr. Leroy wrote a few weeks ago for me and
I modified to meet my requirements. It has one little bug in it and I can't
seem to figure out how to mod this.
1. the code below just sequences a relay closure every time a push button is
pressed connected to (in0), P0, held high with a 10k resistor and switch closed
to ground. It moves one step from relay one to twelve and then back again to
one again every time the switch is pressed.
2. The outputs are from P1 to P12 respectively.
Now, here is the problem,
when the switch is held closed, the relays close in sequence one after the
other. What I want is the code to be modified to NOT move the relay that is
closed UNTIL the pushbutton is released and then in0 sees a ground state again.
here is the code:
outno var byte
loop:
for outno = 1 to 12
inputwait:
high 0
if in0 =1 then inputwait
pause 500
low outno -1
if outno=1 then help
help:
low 12
goto helper
helper:
high outno
next
GOTO loop
Any assistance is always appreciated
thanks to all
sincerely,
mike m

' I think you need to test which pin (relay) is to be activated
' before activating or else when outno = 1 you activate your
' input pin before detecting you're on pin (relay) 1 and that
' it is 12, not 0 that needs to be turned off. Soooo....

I think adding the following two lines will do what you want. After the
relay is activated above, these two lines should loop until the button is
released.
looper:
if In0 = 0 then looper
>next
>GOTO loop
No guarantees, but I think this is what you want, or at least close to it.

Thanks for the help. Stayed up after midnight to try your changes and it
works perfect. I appreciate yours and all the e-group guys help when we are
in need
