The IDE contains an option file editor that can be used to
| • | Create a new options file for a solver |
| • | Edit an existing option file. |
| • | Look up option file possibilities and receive information on settings |
The option file editor is invoked through the IDE utilities>option editor menu choice.
Once in the editor one can use the file menu to
| • | Read an existing option file |
| • | Start up a new one for a particular solver or for GAMS although this seems to have no effect on GAMS execution) |
| • | Save the file |
Once an option file has been read or a new option file started with a solver chosen the user gets
| • | A complete list of all alternatives that can be in the option file for the solver chosen |
| • | A definition of the currently active option and a list of the alternative choices for that option. For example the following screen comes from a new option file after CPLEX was the chosen solver and the option LPMETHOD was scrolled down to |
| • | One can also do a right mouse click or press F2 and get a further definition of the select option as below and in fact this opens a document of all options for the solver at hand. |
| • | There is no attempt in the option file editor to group the options by function and users should still go to the solver guides for that material. This is acccessed through the IDE help menu. |
