Looping AppleScript

I am writing a very basic AppleScript program that I want to always be running in the background. Is the best way to do this just to start the script and have an infinitle loop in it? My program is merely checking if another program is open and if it is it is starting another program. For example, if program A is opened then program B is started.

Is there a better way to write this other than just putting my entire program in a neverending repeat loop?

Thanks

Hmm, having it running all the time wouldn't be too good as it will take a quite a chunk of you CPU power.

I would add a small section to the top of the applescript that you already have that will open program A.
Then instead of opening program A, open the Applescript instead which will open A and then B.

G'day

You do this with an idle handler

save it as an application. make sure you check the 'stay open' option.

as you say, this needs to be always running — the idle handler will repeat your checking script, in this example, every 5 seconds (if you delete the 'return 5' it will run every 30 seconds by default).

Hope this is what you're looking for
