Variables
Here are two ways that you can create your own variables in AppleScript:
set int to 20 -- one way to set a variable to an integer copy 20 to int -- another way
A
variable is a word or identifier that the scripter creates to store a
script value. An example is the int variable in
the statement set int to 20. Along with
copy, the set reserved word is
used to set a variable name to a value, in this case an
integer. AppleScript variables can store any
value, including booleans, lists, numbers, records, strings, and
application-defined classes. AppleScript variables have to begin with
a letter or underscore ( _ ) character, but subsequent characters can
include numbers and underscores. You cannot include operators and
other symbols that AppleScript reserves for different uses (such as
*, &, ^, or +) or special characters (such as $, @, or #). An
exception to this rule in AppleScript allows the creation of
memorable variable names if you use vertical-bar characters (|) to
begin and end the identifier:
set |2$var*&^%#| to 2
AppleScript is not a case-sensitive
language, so the variables that include the same characters but in
varying case are treated as the same identifier. In other words,
myname, myName, and
MYNAME are all considered the same variable.
Variable names can be one to several characters long, depending on
your stylistic preferences.
This AppleScript gives several examples of
valid and invalid variable names, as well as how to use the
set and copy keywords to ...
