Abstract

By offering different sized windows, programs which have differing screen requirements are accommodated. Most existing UNIX* applications require that a full screen (25 lines by 80 columns) be available for output. A problem is created, however, when UNIX and other programs are run in a window which, due to the presence of a command bar and window borders, is less than a full screen. This problem is overcome by providing three classes of windows which an application may use. The classes are characterized as follows: Class 1: 24 lines by 80 characters, including borders (both horizontal and vertical) and a command bar of fixed size. Class 2: 2 sizes: Full screen, 25 by 80 with no command bar or borders, and 24 by 80 with borders and a command bar (allows variable sized windows).

Class 2: 2 sizes: Full screen, 25 by 80 with no command bar or borders, and 24 by 80 with borders and a command bar (allows variable sized windows). Class 3: 25 by 80 with no borders or command bar (size is fixed). * Trademark of AT&T Bell Laboratories.
