When using and teaching the IDE, I find that IDE project location in interaction with file placement gives almost everyone fits at some point or another. I have a rule of thumb to avoid problems.
| • | Make sure that you are working on files located in the same directory location as the project is located. |
| • | This means making sure the path lines match up in the two dark blue locations in the screen shot below. |
You do not have to follow this rule but deviations are the same as asking for trouble. When GAMS executes a file in a different directory it will look for options files, GCK files, include files etc in the directory where the project is located.
Another rule of thumb is also relevant.
| • | Whenever you need to work in a new directory define a new project. |
