Simplified by putting addEllipsis into the menu script.

set the text of cd

I have an Option Menu on a card accessed from other cards where I want to
select item 1 of the menu whenever you go to the card.
The Card that owns Option Menu Button is also accessed from a Tab Panel.
I have this script that is used to setup the button and sometimes it works and
other times

If you replace "sine" with "sin" you also change "cosine" to "cosin" (There is

Hi, Jim and Roger.

Hi Mark
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 write

And in that lies one more reason to use "do" only with great care:

Good points all. I usually try to avoid do whenever I can due to its
inherent slowness and t
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 exists

You should get a field 2 that locks like this, if the angle is 45 degrees::
The sine of 45 degrees is 0.707107
Is that the results you wanted?

I have an Option Menu button with sin, cos, tan as menu Items. I want my card

with that label. I've tried every thing I can think
