Executes an AppleScript script and returns a value returned by the script, if any.
MacScript ( script )
The script argument is a string expression. The expression either can be a series of AppleScript commands or can specify the name of an AppleScript script or a script file.
Multiline scripts can be created by embedding carriage-return characters (Chr(13)).
This example uses the MacScript function to open the Choose File dialog box (the Macintosh standard-file dialog). The full path of the file chosen by the user is returned. If appropriate, the path specification is preceded by the type of the file.
ThePath$ = Macscript("ChooseFile")
