One of the nice features of Gams-Mode for Emacs is the possibility to quickly look up the identifier part of a variable, parameter or set. This is a nice feature in big models or when you haven’t worked with the model for some time. Just put the cursor somewhere on the parameter in the code [...]

Although I am not a great fan of multi-tasking I often use a lot of programs simultaneously for one task: For example, when I am writing a report in Word or with Emacs, I take notes in Emacs, search the internet and have my model results in the gdx-viewer.  Additionally my mail client is somewhere in the [...]

First run your model by hitting C-c C-s (C stands for Ctrl) or use the same command from the menu. Emacs will open a new window and you see how Gams solves your model. When Gams is finished you can hit F10 (or C-c C-v)  to show the listing file in a new buffer. We [...]

First of all download gams-mode from Shiro Takeda’s website: You will find it here: gams-mode-download. The files are zipped and should be unzipped to a directory Emacs will find. I show you my settings (as usual, you can do it in an other way). I have all my additional features in a directory that resides [...]

http://aquamacs.org/. On Windows it is a different story. Emacs is coming from the Unix world and on Windows installing asks for a little bit more knowledge of Windows basics. You can’t for example install an additional feature (like Gams-mode for Emacs) by just double-clicking on a file. You have to move the downloaded files to [...]

GAMS users probably spend most of their time editing their models. Just before project deadlines they may sit more than 8 hours a day in front of their computer hacking through their code. The choice of a good editor can therefore be crucial. After years of trying different editors I finally stuck (xxx) with the [...]
