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

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

1. In Visual FoxPro, run the following code from the Command window.

NOTE: You need to provide the actual servername, user ID, and password for your
installation of Microsoft SQL Server.

  ?SQLSTRINGCONNECT("Driver=SQL Server; Server=servername;uid=sa;pwd=;")
  ?SQLEXEC(1, "sp_who")
  BROWSE

In the Browse window, you may see a box or other ASCII character at the end of
the status field, depending on the font that is used by the window.

2. Close the Browse window.

3. In the Command window, type the following:

  ? ASC(SUBSTR(status,LEN(status),1))

The Visual FoxPro command has embedded a NULL (CHR(0)) as the last character in
the status field.
