Another way, if you want ot have a 'stop' button, for instance, is to  
have a script local variable that you set from a button :

in the stack or card script that runs the loop:

local sStopLoop = false

on someFunction
    repeat until jobDone
      if sStopLoop then exit repeat
      doStuff...
      wait 0 millisecs with messages -- need this to allow rev to  
respond to button clicks
    end repeat
    cleanUpStuff...
end someFunction

on stopLoop
   put true into sStopLoop
end stopLoop

Then in the stop button script:

on mouseUp
   stopLoop
end mouseUp
