   Switch           Function
   ----------------------------------------------------------------------

   /e, /embedded    Forces Excel to start without displaying the 
                    startup screen and creating a new workbook 
                    (Book1.xls).

                    Example: /e or /embedded

   /m               Forces Excel to create a new workbook that
                    contains a single macro sheet.

                    Example: /m

   /o               Forces Excel to re-register itself. Specifically, 
                    the following key is rewritten in the registry:

                    Excel 97: HKEY_CURRENT_USER\Software\Microsoft\Office\8.0\Excel
 
                    Excel 2000: HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Excel

                    Excel 2002: HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Excel

                    Excel 2003: HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel

                    NOTE: If this key contains values that are not valid,
                    they are not corrected by using this switch. This 
                    switch only replaces missing values.

                    Example: /o

   /p <folder>      Forces Excel to use the path that you specify as the active
                    path instead of the default path. 

                    Example: /p "C:\Windows"

   /r <file name>    Forces Excel to open the specified file in
                    read-only mode.

                    Example: /r "C:\My Documents\Test.xls"

   /s, /safemode    Forces Excel to bypass all files in the Application Data\Microsoft\Xlstart folder,
                    the default XLStart folder located in the directory where Excel or Office is installed, 
                    and the alternate startup file location specified on the General tab of the Excel Options dialog box. 
                    It also forces Excel 
                    to bypass the toolbar file (Excel.xlb or 
                    <username>.xlb). You see "Safe Mode" in the 
                    Excel title bar. Use this switch when you want to 
                    start Excel in safe mode.

                    Example: /s or /safemode
				

     /t                Forces Excel to use the specified file as a
                    template for the default workbook. 

  /regserver        Forces Excel to register itself and then quit. Use this 
                    switch when you want Excel to rewrite all its 
                    registry keys and reassociate itself with Excel files, 
                    such as workbooks, charts, and others.

                    Example: /regserver


   /unregserver     Forces Excel to unregister itself and then quit.

                    Example: /unregserver
