XL97: Run-time Error Evaluating Immediate Window Expression

• Microsoft Excel 97 for Windows

SYMPTOMS

When you type a mathematical formula similar to the following in the Immediate window in the Visual Basic Editor:

   ?200*200

   Run-time Error 6:
   Overflow

CAUSE

This problem occurs when the result of the calculation you type in the Immediate window is too large to be represented by an Integer type expression; the result exceeds the limit for the Integer type expression.

RESOLUTION

To resolve this behavior, assign the Long integer data type to any mathematical functions that return a value larger than 32,767. To assign the Long integer data type in the Immediate window, use the ampersand (&) character. The following example illustrates the syntax to use:

   ?200&*200

STATUS

This behavior is by design of Microsoft Excel 97.

MORE INFORMATION

Long integer variables are stored as signed 32-bit (4-byte) numbers that range in value from -2,147,483,648 to 2,147,483,647. The type declaration character for Long is the ampersand (&) character.

Integer variables are stored as 16-bit (2-byte) numbers that range in value from -32,768 to 32,767.
