Q154981: PRB: AppleScript: "Results" are Not Implemented

Article: Q154981
Product(s): Microsoft FoxPro
Version(s): MACINTOSH:3.0b
Operating System(s):

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual FoxPro for Macintosh, version 3.0b 
-------------------------------------------------------------------------------

SYMPTOMS
========

AppleScript returns the message "the variable x is not defined" when it tries to
execute the "set x to result" command. "Result" is a predefined variable in
AppleScript. It contains the results of the most recently evaluated expression
or the most recently executed command. If a command returns nothing, the result
is not defined.

CAUSE
=====

An equal sign (=) placed in front of a function tells FoxPro to compile the
function as a command. However, commands have no return value in FoxPro. The
equal sign tells the compiler that the return value is to be ignored because it
is not being assigned to anything.

RESOLUTION
==========

Do not use an equal sign in front of the function. The result variable will then
be assigned to the value returned by the function.

STATUS
======

This behavior is by design.

MORE INFORMATION
================

Steps to Reproduce Behavior
---------------------------

Run the following AppleScript:

     Tell Application "Microsoft Visual FoxPro"
        Activate "Microsoft Visual FoxPro"
        Do Script "=DATE()"
        Set x To Result
        QUIT
     End Tell
     Display Dialog x

AppleScript returns the message "the variable x is not defined" when it tries
execute the "set x to result" command.

Remove the equal sign, and the dialog will display the date.

NOTE: FoxPro must be activated for "result" to be assigned the value of DATE().
Also the "Display Dialog x" should be placed after the end tell. If placed
inside the End Tell statement, FoxPro will not quit because it loses focus
before it has a chance to quit.
