Ensure macros enabled - C. Pearson's sheet visibility method

I am using Chip Pearson's sheet visibility method for ensuring the macros are
enabled (http://www.cpearson.com/excel/EnableMacros.aspx).
I need to modify it so more than just the Introduction sheet are visible
when macros are enabled.
The sheets that I want to appear when macros are disable are:
About, Requirements, Charts, ListANoMacros, and ListBNoMacros.
When Macros are enabled I want to see About, Requirements, Charts, ListA,
and ListB.
The bulk of the code goes into a general module, which I've tried tweaking,
but I just got a big mess; so I've just pasted the original code from Chip's
site below.


Private Const C_SHEETSTATE_NAME = "SheetState"
Private Const C_INTRO_SHEETNAME = "Introduction"
Private Const C_WORKBOOK_PASSWORD = "abc"

Sub SaveStateAndHide()

' SaveStateAndHide
' This is called from Workbook_BeforeClose.
' This procedure saves the Visible propreties of all worksheets
' in the workbook. This will run only if macros are enabled. It
' saves the Visible properties as a colon-delimited string, each
' element of which is the Visible property of a sheet. In the
' property string, C_INTRO_SHEETNAME is set to xlSheetVeryHidden
' so that if the workbook is opened with macros enabled, that
' sheet will not be visible. If macros are not enabled, only
' that sheet will be visible.
