Hi Dale,

Welcome to the Revolution -- this mailing list will

One excellent bit of information is the HC-to-Rev
tutorial that Jacqueline Landman Gay has written :

First you have to turn on the 'Debug mode' in the menu
'Development', select 'Script Debug Mode' if it
doesn't have a checkmark in front of it.

In the same menu, you'll also find the Message and
Variable Watchers.

You can make the debug kick in by using the keyword
'breakpoint' in your script :
--
on mouseUp
  put 5 into x
  ## we want to stop right here
  breakpoint
  ## now you can step or trace through the rest
  answer x
end mouseUp
--

However, these are permanent ; the Revolution script
editor also allows you to set temporary breakpoints by
clicking on the grey area to the left of the script.
When you click there, a red dot will appear, and upon
execution, the script will halt there.

The script editor doubles as debugger, and when you
hut a breakpoint, the bottom of the screen will show
buttons "Step into", "Step over", "Trace", "Run" and
"Abort"

As for lending a hand, I'm currently too swamped with
work and evening classes ; but there might be others
on this list to take you up on that offer.

Hope this helped,

Jan Schenkel.
