How to abort from subroutine directly..?

Scripting Forums AppleScript | Classic Mac OS
#1

I am running a script from the Finder, i.e. from an Apple Contextual Menu. The script needs to be aborted under some conditions found in subroutines. However, using a command such as “return” only breaks the subroutine, not the main loop. Calls like “quit” and “abort immediately” will quit the Finder - which is not what should happen.
How can I do this…?

You don’t mention trying “error number -128”

Use the ‘error’ keyword to throw an error.

if (someValue is "broken") then error "I'm going to cry now."

See the AppleScript Language Guide for more details - there’s a ton of stuff you can do with ‘error’.
