SYMPTOMS

Using the VAL function on a large hexadecimal number (greater than or equal to the hexadecimal value 80000000) embedded in a string can incorrectly cause a "Type mismatch" error. This occurs only when the hexadecimal number contains an ampersand (&) at the end of the string.

WORKAROUND

To reproduce the problem run the following code:

   PRINT VAL("&H80000000&")

You get a "Type mismatch" error. To prevent the error, remove the last ampersand (&) character.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem has been corrected in Visual Basic version 4.0.
