SYMPTOMS
========

When you programmatically set the Value property of a text box that has its
ControlSource property set to a field in a table, a new record will be added to
the table if the record pointer is positioned at the end of file.

WORKAROUND
==========

If the Value property of a text box is to be set programmatically, use the EOF()
function to determine if the record pointer is positioned at the end of file
before setting the Value property.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products listed at
the beginning of this article. This problem has been fixed in Visual FoxPro 5.0
for Windows.

Steps to Reproduce Problem
--------------------------

1. Create a new form.

2. Add a table to the data environment of the form.

3. Drag a character field from the table in the data environment to the form.

4. Add a command button to the form.

5. Add the following code to the Click event of the command button:

     GO BOTTOM
     SKIP 1
