Thus far, data in AGRODEP GAMS training has been introduced through direct assignments only. Lesson 7 introduces users to new methods for importing and exporting data files. Import methods include creating GDX files through conversion tools and importing directly from Excel. Data export methods also include exporting directly to Excel files, as well as using the PUT facility to create output files that can be opened in Excel. The ability to call multiple “.gms” files while running one program is also explored in this lesson.
