Exiting from loops

Hi I was wondering if there is a way to exit out if you accidently get into one of these situations (other than force quitting and losing unsaved stuff):
Code: Select all
repeat until x = 1
answer "Hi"
end repeat
Thanks

Welcom grc,
Code: Select all
repeat until x = 1
answer "Hi"
wait 0 millisec with messages
end repeat
this will let you comand period or escape out of the loop

Bernd, that would be ideal but unfortunately the command-. option isn't available for dialogs:

The workaround is to check for escaping in the repeat loop.

Richard,
thanks for pointing me to the bug report.
Actually what I thought the question was is how to get out of an infinite repeat loop. Not really thinking about aborting the answer dialog.
Adding 'wait 0 millisecs with messages' will get you out of an infinite repeat loop, even the one with the dialog, but only after hitting command - period quite often after the the ok button of the dialog.
So where does that leave grc?
for a normal repeat loop wait 0 etc
for a dialog in a repeat loop I suggest to put something like this
Code: Select all
repeat until x = 1
answer "Hi" with "Cancel" or "OK"
if it is "Cancel" then exit repeat
end repeat
regards
Bernd

One of the things I do (particularly in development) is to check for the option key during the loop:
Code: Select all
repeat until x = 1
stuff that hopefully eventually results in x = 1 :)
if the optionkey is down then exit repeat
end repeat
Then, when I've set off a runaway loop, I can just hold down the option key.
Best,
Mark Smith
