SUMMARY

In the versions of Microsoft Excel listed above, the following Microsoft Visual Basic for Applications Help example for the Sub statement contains an incorrect variable: 
    Sub SubComputeArea(Length, Width)       ' Sub with two arguments.
       Dim Area As Double                  ' Declare local variable.
       If Length = 0 Or Width = 0 Then     ' If either argument = 0.

           Exit Sub                        ' Exit Sub immediately.

       End If

       Area = Length * Width               ' Calculate area of rectangle.
       Debug.Print Area                    ' Print Area to Debug window.

   End Sub
In the example, a variable called Width is used. Width is a reserved keyword in Visual Basic and cannot be used as a variable.

NOTE: This problem does not occur in the Help files included with Microsoft Excel 97 for Windows and Microsoft Excel 98 Macintosh Edition.

WORKAROUND

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. Changing each reference to Width in the example to gWidth (or another variable name that is not reserved) will allow the example macro to function correctly. The following example is a corrected version of the sample procedure: 
   Sub SubComputeArea(Length, gWidth)      ' Sub with two arguments.
       Dim Area As Double                  ' Declare local variable.
       If Length = 0 Or gWidth = 0 Then    ' either argument = 0.

           Exit Sub                        ' Exit Sub immediately.

       End If

       Area = Length * gWidth              ' Calculate area of rectangle.
       Debug.Print Area                    ' Print Area to Debug window.

   End Sub
