In HC that was done by default which I found to be very handy. And
that is all I have to say about IT.
I'm not sure "it" is global in HC, at least not in any normal sense
of what global usually means.
I just made two buttons on my HC Home stack -
-- Button 1:
on mouseUp
get "hello world"
end mouseUp
-- Button 2:
on mouseUp
put it
end mouseUp
When I click Button 1 and then click Button 2, the Message Box
contains "it", not "hello world" as we would expect if "it" were
global.
If I add global declarations for "it" in both handlers, it does
work as expected, but then I believe the same is true for Rev.
If I recall correctly, "it" was sort of a "message box local"
variable. You could do things like this in the msg box:
answer "test" <return>
put it <return>
The contents of "it" would appear in the msg box. It doesn't work
like this in Rev; you have to go to the multiline message box.
