[OT] Why would it be a pain?

[Dan Shafer]

Clearly Rev and HC work differently with regard to IT.

I'm not sure, Richard, that an example that "gets" a string -- a perfecty
legal but bizarre-seeming use of the "get" command to me -- really
demonstrates globalness or the lack thereof.

Having said that, I elaborated a bit on your example just to see what would
happen.

on mouseUp
  get 23
  putit
end mouseUp

on putit
  put it
end putit

That puts the word "it" into the message box.

But if I change put it so it looks like this:

on putit
  answer it
end putit

the dialog is empty.

So what is it that putit is putting when told to put it? Is it the string
"it" rather than the name of the variable? I'm not even sure how to find
out. Every time I try, I end up in a circularity.
