This article was previously published under Q182296





SYMPTOMS
When you run a Visual Basic for Applications macro in Microsoft Excel 98 Macintosh Edition, you may receive the following error message:

Run-time error '6':

Overflow



CAUSE
This problem may occur when all of the following conditions are true:

  You set the value of a variable equal to the value of the Err object in the macro; the following is a sample statement: ErrNum = Err 

-and-


 * You dimension the variable in question as type Integer.

-and-


 * You use the Raise method of the Err object (Err.Raise) to generate a run-time error that has a value greater than 32767 or less than -32768.

To work around this problem, dimension variables that will contain Err values as type Long. For example, instead of using Dim ErrNum As Integer use: Dim ErrNum As Long This code ensures that you do not receive the overflow error message.



STATUS
This behavior is by design of Microsoft Excel 98 Macintosh Edition.



MORE INFORMATION
In Microsoft Excel, the Err object contains information about run-time errors that occur when you run a Visual Basic macro. You can determine the value of the last run-time error that occurs by reading the value of the Err object. For example, the following line of code sets the variable (ErrNum) equal to the value of the last run-time error that occurs:

ErrNum = Err

You can use the Raise method of the Err object to generate a run-time error with any value. For example, to generate a run-time error whose value is 50000, use the following code: Err.Raise 50000 If you use this code and set the value of a variable equal to the value of the Err object, as in the following code: ErrNum = Err you receive an overflow error if the variable (ErrNum) is dimensioned as type Integer.

NOTE: All run-time errors generated by Microsoft Excel 98 Macintosh Edition should have a value between -32768 and 32767. Therefore, you receive an overflow error only after you use Err.Raise to change the value of the Err object to a non-Integer value.
