You can define your own way of formatting for other modes. For gams-mode you add the following to your .emacs file
Many professional editors have a column guide. For example, below you see in the Powershell editor a veritcal line at column 80.
This marker comes in handy, if you want to print your files. In Emacs I usually check for the column 80 in the status line.

Gams-mode has another great outline feature for the listing file. Instead of putting a normal comment with a “*” in front, one writes a display statement that starts with a “@” (see the code above). We now see a nice heading … Read the rest “Using org-mode in outline-mode”
