The Guide mentions constant, I remember being brought up that

For instance
set pi to 3
makes pi=3!!!
But I was not aware that one could set other constants as well
The new Guide is less unclear on the meaning of "constant" than the
old one, but you have to read rather carefully. I assume you're
referring to the Global Constants in AppleScript section -- if you
look, you'll notice that it says that "AppleScript" is a constant
referring to a script object with a variety of properties, which are
all writable. In other words, "AppleScript" itself is a constant --
you can't set it to something else. That doesn't mean that the object
it refers to is a constant, however. If you're familiar with modern
C, this is similar to the distinction between "const T *" (a mutable
pointer to a constant T) and "T * const" (a constant pointer to a
mutable T).
Another point, even when using "local" declaration, the variable is
kept on the script. Which is kind of weird considering the example I
posted. The following
set mypasswd to "bomdia"
will show "bomdia" on your script whether it is declared as local or
not.
That is save the script above and open it in TextEdit. "bomdia" will
be clearly readable.
This differs than what I'd expect using "local".
You're assuming that that value is stored in the local variable. It
isn't. You're looking at the value of "result" global, which, as a
global variable, is archived.
