The EXTERNCOUNT record specifies the number of externally referenced workbooks, DDE references, and OLE references contained in a Microsoft Excel workbook.
For example, a worksheet contains the following formulas in cells A1:A3:
=SALES.XLS!Profits
=Signal|System!Formats
=Signal|StockInfo!MSFT
This worksheet would have a value of 3 in the cxals field of the EXTERNCOUNT record, corresponding to the three external references SALES.XLS, Signal|System, and Signal|StockInfo.
