return [return value]
The return statement returns values from functions
or subroutines, just as it does in Perl and JavaScript. If you finish
a function definition with just return, with no
subsequent return value, then the function will return to where it
was called in the script without returning an actual value. You can
return any value, such as a number,
string, boolean, or
list:
return true
If you do not use return at all in a function then
the return value of the function will be the result of its last
statement, if the statement returns a result. (Chapter 9 is devoted to developing functions in
AppleScript.)
If you define a function with just return without
a value and then try to set a variable to the return value of that
function, the script will raise an error.
Make sure not to confuse the return statement with
the return predefined variable, which is a return
character in a string such as:
set theString to return & "Start a new line"
