ABSTRACT A method to maintain all information originally displayed in a window on a display screen as the size of the window is varied. By selecting from a plurality of different character sets that are stored in the system, a character set is obtained which has the appropriate width and height attributes that allow the original text characters to be substituted for the corresponding text characters originally displayed. Since the selected character set contains proportionally smaller characters no information is lost when the size of the window is decreased. The different character sets that are stored may be hardware implemented or software generated character sets which are also based on different sized character sets. The type of font is important only in the context that some fonts are more readable as the size of the characters decrease than others. The method allows the operator to dynamically vary the window size after the initial window has been displayed in response to some predetermined action by the operator. The amount of decrease in window size is calculated in real time by monitoring the movement of mouse and cursor position. A table is stored in memory which lists all of the displayable character sets that are available. Each character set has a width attribute and a height attribute. A percentage decrease in width and height is stored in the table representing changes from the corresponding attributes of standard character set that is normally used to display information in the system. A new character set is selected from the table in accordance with the calculated percentage of decrease DA9-87-015 and the new character substituted in the text. If the user decides to restore the window to its original size, a 1-step key or mouse button sequence is available. DA9-87-015
