Word processing at a display terminal allows text to be entered and edited by the operator. This text is often stored within the terminal for further editing. In addition, it is usual for the operator to enter text formatting commands. These are used to control the 'shape' of the text when displayed or printed. The internal representation of the text commands may be markedly different from the form keyed by the operator. In some representations the commands are stored as a sequence of binary numbers. Clearly it is an advantage to obey the commands as they are entered. The operator can immediately see the effect of the command on the shape of the text presented on the screen.
