GDXXRWExample6 : Reads a two dimensional parameter from an MS Excel file and writes it to a GDX file


This program illustrates reading a table from an Excel
spreadsheet. It contains the same data as in GDXXRWExample5.gms
which is organized differently. Unlike GDXXRWExample5.gms,
this example also reads set data. Additionally, this program
offers writing and reading GDXXRW command options from a file.
