DISPLAY SUPPORT OF INDEFINITE PAGE

A text processing system includes a first external storage area for text documents, an internal text storage buffer where, inter alia, edit operations are performed, and a third storage area in which text is formatted for display. The area for formatting text for display is related to the internal text storage buffer by a table containing pointers to the text storage area, one for each line to be displayed. The pointers are expressed relative to a single known address, that of the start of the line in the text storage buffer containing the point at which the edit operation is to occur.
