modules. These are attached to the Word document (usually called
'ThisDocument'), the Excel workbook (usually called
'ThisWorkbook'), or single Excel worksheets or chartsheets (usually
called 'SheetX' or 'ChartX', X being a decimal number). Of course,
users may rename all these modules. The slash character separates
an automation server version number (hexadecimal 'XXXXXXXX') from
the module name.

modules.
