Now you are ready to work with your own files. You may already have a file or you may need to create one. There are two principal ways to do this:
| • | Open an existing GMS file. Then with the file menu save as dialogue change it's name. Now modify the contents to what you want. You may cut and paste as in other Windows programs. |
| • | Open the file menu and use the new option. You will then get a file called noname which you may type GAMS instructions into |
when you are finished save that file with whatever name you want. Note by default it will be assigned the extension .GMS.
