Q189916: BUG: SET("DEBUGOUT") Returns Filename After SET DEBUGOUT TO

Article: Q189916
Product(s): Microsoft FoxPro
Version(s): WINDOWS:5.0,5.0a
Operating System(s): 
Keyword(s): 
Last Modified: 11-DEC-1999

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

- Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a 
-------------------------------------------------------------------------------

SYMPTOMS
========

You issue a SET DEBUGOUT TO <some filename> to direct debug output to a
file. Subsequently, you issue a SET DEBUGOUT TO to direct output to the Debug
Output window. If you then check the return value of SET("DEBUGOUT"), it will
continue to indicate that DEBUGOUT is directed to the file.


STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. We are researching this bug and will post new
information here in the Microsoft Knowledge Base as it becomes available.

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

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

1. Run the following code from a program (.prg) file:

        CLEAR
        ?1, SET("DEBUGOUT")
        SET DEBUGOUT TO TestDebg.Txt
        ?2, SET("DEBUGOUT")
        DEBUGOUT "Set to file"
        SET DEBUGOUT TO
        DEBUGOUT "Not set to file"
        ?3, SET("DEBUGOUT")
        MODIFY FILE TestDebg.Txt NOWAIT

The file TestDebg.txt will be displayed containing the text "Set to file." This
is expected behavior. The SET DEBUGOUT TO is working properly, as the second
DEBUGOUT statement is not sent to the file.

You will get the following output printed to the screen:

  1
  2 <current drive and directory>\TESTDEBG.TXT
  3 <current drive and directory>\TESTDEBG.TXT

This is not expected behavior. The line following the 3 should be empty, as is
the line following the 1.

You may change the SET DEBUGOUT TO <another file>, and SET("DEBUGOUT") will
then return the new file name, but to clear the return value, you must restart
Visual FoxPro. Otherwise, SET('debugout') will return the most recent file name
it was set to for the remainder of the Visual FoxPro session.
