How do I interrupt and cleanup gracefully?

[T. R. Ponn]

Jan,

I tried it and it failed (the IDE locked up)...then I added the obvious 
(exit to top).  And, just to make sure things were back where they're 
supposed to be, I added "set allowInterrupts to true".  Badda-bing! 
 That did it!

Though not a biggie, I'm still struggling with understanding the logic: 
set allowInterrupts to false = allow the user to interrupt.  Sounds 
backwards to me. :-D

Thanks!

on mouseUp
  put empty into msg
  set the allowInterrupts to false
  repeat
    if the interrupt
    then cleanThisUp
    else add 1 to msg
  end repeat
end mouseUp

on cleanThisUp
  put "I'm interrupted" into msg
  set the allowInterrupts to true
  exit to top
end cleanThisUp


Best Regards,

Tim Ponn
