Now we want to work with an input file. Several cases are possible for the source of this file
| • | You can create a new file |
| • | You can open an existing file using the file open dialogue |
| • | You can open a GAMS model library file using the file Model library dialogue |
The last is the simplest and the one we illustrate first. Select a model like trnsport.gms by scrolling down or typing the name trnsport in the search box until it is the chosen one
In turn this file will be automatically saved in your project directory (this is the directory where the project file is located). Note outside the IDE this is done using the command line instruction gamslib modelname or in this case gamslib trnsport.
