Passing parameters by reference

[Dar Scott]

Thanks for the tip, Dick, on using the list of keys.  One can think of arrays as nested or multidimensional.

Though is is probably more work, one might also consider chunks in pass-by-reference.

Maybe any thing the subtract command can take.

However, this might be a problem:

doSomethingToTheseTwo char 1 to 2 of it, char 2 to 3 of it

command doSomethingToTheseTwo @a, @b
	put "butter" into a
	put "cheese" into b
	put empty into a
end doSomethingToTheseTwo

That might also have a problem with this call:

doSomethingToTheseTwo x, x["t"]

I immagine LiveCode folks can come up with a semantics that makes sense for weird cases.  

The subtract command does not have the the problem because it modifies only one thing.
