When GAMS runs it automatically opens the LST file and a navigation window as identified in the red box below. By clicking on lines in the lst file navigation window you can access program output both in general and at particular locations.
The positioning of the cursor in the LST file is determined by the type of line you click on. A list of types of lines typically in the LST file is given below and the contents of this will be defined below..

The width of the LST file navigation window is controlled by the user and can be narrowed as it has been above.
The data for this is stored in a LXI file that will be resident in your project directory with the same root as the associated LST file.
