Thanks Trevor,
It works great!
I also wasn't aware of Script Local Variables (You can declare them at the beginning of a script and all the handlers in the script can recognize them). Cool stuff!
Thanks again.

I'm trying to implement a status window in an app I'm building.
I'd like to user to click a "Process" button and have the app open a status window indicating the status of the stuff they are processing (with a progress bar, cancel button, and other useful information). The main script for the processing is located in a sub stack where the main interface is located. I thought I could just open the status stack, have a button on that stack that sets a global to cancel the process, and have the processing script check the global each time it processes an item. Here's basically what the processing script looks like:
repeat with x = 1 to theNumberOfItems global gCancelStuff processStuff theItem if gCancelStuff is true then exit to top end repeat
The problem is the script prevents all interaction to buttons until it has completed processing all of the items. Is there a way to script it so the Cancel button can be clicked (and the process aborted)? Is there an example stack somewhere I can learn from?
Dave,
Maybe try using send rather than a repeat loop. Something like the following may give you the results you are after.
local sNumberOfItems local sItemCounter
on startProcessing --> SET UP COUNTERS put 20 into sNumberOfItems put 0 into sItemCounter
send "processStuff" to me in 0 seconds end startProcessing
on processStuf add 1 to sItemCounter
-- do stuff to item sItemCounter if sItemCounter < sNumberOfItems AND gCancelStuff <> true then send "processStuff" to me in 10 milliseconds end if end processStuff
