Version(s): WINDOWS:3.0,3.0b,5.0,5.0a
Operating System(s):

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

- Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a 
-------------------------------------------------------------------------------

SYMPTOMS
========

If the length of the string assigned to x with the x=replicate("X",105) command
is less than or equal to 88, then ?set('topic') returns a blank. Note that
set('topic') returns values only when the length of the string assigned to x is
longer than 88 characters in an incremental fashion. For example, if you use
x=replicate("X",89), set('topic') returns 1(one) x. If you use
x=replicate("X",98), set('topic') returns 10 x. So, the value returned by
set('topic')=(LEN(x)-88).

WORKAROUND
==========

Do not use messages greater than 88 characters.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products listed at
the beginning of this article. We are researching this problem and will post new
