Control structure with "not"

[Peter Haworth]

Maybe I'm misunderstanding what you want but I think my code does that.

For example, let's say tSender is "Apple":

set tSwitchApple to (tSender is not "Apple") --> false
set tSwitchPeach to (tSender is not "Peach") --> true
set tSwitchGrape to (tSender is not "Grape") --> true

Looking at your code again, it's unclear as to whether your tSwitchxxx
things are variables or custom properties.  Using "set" makes me think they
are custom properties but then you would need "of <objectreference>" or the
script won't compile. If they are variables, then use "put" to put values
into them.

If they are variables, I'd make the switches into an array and then:

repeat for each item rFruit in "Apple,Peach,Grape"
   put (tSender is not rFruit) into tSwitches[rFruit]
end repeat

And I really like Phil's "split" solution!
