Description

In this example GAMS runs only in the background. We use the vba version of the
GDX API to write a GDX file from data defined in the spreadsheet. With 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 the workbook
using the GDX vba API again.
