Description

In this example GAMS runs only in the background. We use gdxxrw to write a GDX
file from data defined in the spreadsheet.With the vba version of the
option object API we set several GAMS options from vba and solve the model
using the gams executable. At the end the solution is written into a user defined
workbook using gdxxrw again.
