8.1.1 Language Concepts

During the run of gtroff, the input data is cracked down to the information on what has to be printed at what position on the intended device. So the language of the intermediate output format can be quite small. Its only elements are commands with and without arguments. In this section, the term command always refers to the intermediate output language, and never to the gtroff language used for document formatting. There are commands for positioning and text writing, for drawing, and for device controlling.
