Hold down switch to make led light up.

Hi

When you push down on pin [noparse][[/noparse]23], it runs the program (pub Right), and repeats it over and over, till you let go of the switch.
Is there A way that I can program it, so when you hold down the switch, it will run to the end of the (pub Right), and stop with all
the (outa[noparse][[/noparse]0..19] := %11111111111111111111) On. Then when you let go of the pin [noparse][[/noparse]23], it will go to off. (outa[noparse][[/noparse]0..19] := %00000000000000000000).

So what I am shooting for. The same way the brake works.

pin held down (22 ON) = All Pin's are on ( outa[noparse][[/noparse]0..19] := %11111111111111111111)

pin (22 off) = ( outa[noparse][[/noparse]0..19] := %0000000000000000)

Thank you.

Just put this at the end

REPEAT WHILE ina[noparse][[/noparse]23] == 1

and it will stay there until you let go of the button.

And then you should maybe think of a better way to do the same thing using a loop and some boolean operations. What you need is:
1. a loop
2. a variable which has the least significant bit set to 1
3. shift the bit with each iteration
4. write the bit to the outa

Of course you have to find the right order ;o) .. and the right operation to 'write' it to the outa ...

And then compare the longs needed in your first version and in the loop version.

By the way ... dira is only needed once, as long as you run the code in the same COG. So, I'd move it to the main program in your case and remove it from both functions.
