What would be the best way to enum unknown spreadsheet tab names or number and touch each tab?
something like

 oExcel=CREATEOBJECT("Excel.Application")
 With oExcel
         .DisplayAlerts= .F.
         .WorkBooks.Open(XLSFile,0)
         FOR iTabor= 1 TO 100
            .Sheets.iTabor.Select()

         ENDFOR
