ABSTRACT:
An improved photocomposition machine is provided including a keyboard and a cathode ray tube (CRT) which displays various function commands, such as font, point size, and line length and their selected values, in a function field area on the CRT screen. Changes in point size and font values made by the operator within a line appear on the screen with the type line characters in a sequence which they were entered. Upon completion of a type line, the last selected point size and font values appear in the function field area as the completed line is shifted to a predetermined location on the CRT screen, whereby the operator is provided with a visual record of the point size and font values for both current and previous lines.
