Chapter 6. Variables and Constants
This chapter describes the rules for AppleScript variables, including
variable scope and the special variables that you
can add to your script called properties. The
second part of this chapter is devoted to
AppleScript’s predefined variables such as
pi and current
application (a constant). These AppleScript
variables are called constants because their
value is predefined, and you mostly cannot use the same words for
your own script variables. You could name one of your own variables
pi (a predefined variable) and get away with it,
but this would only confuse the readers of your code.
