BUG: SET TOPIC Overwritten by SET MESSAGE

ID: Q136042

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 information here in the Microsoft Knowledge Base as it becomes available.
