Format Pages On Demand And Save in Temporary Document

      This article describes a method of formatting pages of a
document in the most efficient manner to give the user the best
response time when viewing the formatted pages.

      The DisplayWrite* View Formatted Document function allows the
user to view the document as it will be printed. Fonts, line ending
decisions, headers and footers are displayed on the screen just as it
