Abstract

A proportional spacing algorithm is disclosed in which an increased number of characters is to be fitted into a line with a limited resolution. This is provided by adjusting the intervening spacing according to the actual versus the theoretical position of the characters subject to the constraint of having fixed and variable position characters so that tabular data does not become misaligned. Also considered is the case where fixed position data would lead to maximum line length being exceeded. It is sometimes highly desirable to display data on a device that strictly speaking does not have sufficient resolution. For example, it may be necessary to display data from an 80-column display screen on a device that has only 320 picture elements (pels) across.
