Thanks embedded, it works just as you describe it.

Is there a way to print out a block of ruby code in flowstone? I tried selecting the code but the copy function is grayed out. If I could copy it I could then paste it into a text program and print it out. My program is getting longer and longer and I would like to document it.

I see how the repeating if statement is equivalent to a while statement but I have not found a way to break out of the event method. If I add a "break" statement in the else loop I get an invalid break error. See below.

else
output 0, "Not Looping"
@count = 0
output 1, @count
break if @ins[0 ...

Thanks for the very useful code, I see the delay is working and definitely needed, if I reduce it from .01 to .001 flowstone has an error.

I tried the event method you provided and I see how it continuously loops, but is there a way to exit out of that loop? Like a while statement I want to loop until a condition is met, perform an action, then exit out of the loop.

I am converting qbasic code that uses while loops and is working fine ...

I wanted to use a while statement to loop in ruby until a limit switch was pressed.
Ruby gives an error : "excessive processing detected"
See code below:

while @ins[0] == false do
end

Please advise how to suspend operation until an event occurs.

Including sleep 10 in ruby code causes an error:
excessive processing detected. This ruby component has been turned off.

Should the sleep command be avoided in Ruby?

I agree more documentation for Ruby is needed, as an example I could not find the following Ruby method mentioned in the User Guide: v.drawBitmapSection
This method is in the vintage LED Ruby code for the draw knob module.

Thanks for the tip on Ruby and providing a less complicated menu selector. I agree my menu selector was overly complicated and getting more so as I added more menu items!

I added an image file for the controller.
