at the place in the script where the handler was called, using the value returned
as the value of the handler.
SYNTAX
return expression
where
expression is an AppleScript expression. When AppleScript executes a Return
statement, it returns the value of the expression. Expressions are described in
Chapter 6, “Expressions.”
EXAMPLE
To return a value and exit a subroutine, include a Return statement in the body
of the subroutine. For example, the following statement returns the integer 2:
return 2
If you include a Return statement without an expression, AppleScript exits the
subroutine immediately and no value is returned.
NOTES
If a subroutine does not include a Return statement, AppleScript executes the
statements in the subroutine and, after handling the last statement, returns
the value of the last statement in the subroutine. If the last statement does not
return a value, then no value is returned.
When AppleScript has finished executing a subroutine (that is, when it
executes a Return statement or the last statement in the subroutine), it
passes control to the place in the script immediately after the place where
the subroutine was called.
