It turns out that Do is fast enough. Here is the Do script:
(The script might read a litle better by using x in the repeat loop instead
of i.)
on mouseUp
put the label of btn myOptionMenu into tTrigFunction
--It might be necessary to take care in using the following replacements
This script is amazingly fast! And so are you, having apparently produced it in
less than an hour!! My script appears to be slightly slower using a switch/case
structure. I'll test it out when I get a moment.
Thanks very much,

Hi, Jim and Roger.
If you like more concise code, you can code the above like this:
put value( tTrigFunction ( tAngle ) ) into y

Ah yes, I had a vague recollection of this but couldn't quite get it right.
I love it!

Yes, although the value function can do more than it does in this example
(see the dictionary for details).

Well, Mark, maybe not so flexible. For example, to use Do with the arctan()
function in LC, as you suggest, would require you to replace the arctan text
with atan text, or more likely the atan2 text, as that is how LC expresses
that trig funciton.
That might not be easy if arctan text

Never mind what, just Do it.

I can recall one case where Do was the perfect solution for me.
It was a tutorial to help students understand the physics of the rainbow.
It provided them with a mini-programing language, that allowed them to control
how a ray of light might interact with a drop of water.
They would

If your script is triggered by a change of the option menu, then this format
