   This program reads set data using xls2gms.exe.

   The Windows GAMS distribution contains several tools to exchange data with MS-Excel:  
   GDX2XLS, GDXXRW, XLS2GMS, and XLSDUMP. While we continue to include all four tools in our 
   distribution, only GDXXRW is under active development.  Therefore, we strongly recommend 
   using GDXXRW for data exchange with Excel.
