XL: DocErr: VB for Apps Sub Example Incorrect

Last reviewed: February 3, 1998
Article ID: Q113046

The information in this article applies to:

Microsoft Excel for Windows 95, versions 7.0, 7.0a
Microsoft Excel for Windows, versions 5.0, 5.0c
Microsoft Excel for the Macintosh, versions 5.0, 5.0a

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.

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
