Notes File Format

               The  Notes file created by the Notepad desk accessory has  a
          VLIR  file  structure.  Each  branch  is a  single  sector  which
          comprises a page of the notepad.  This sets the notepad's  limits
          to 127 pages of 253 characters. 127 pages because of the limit to
          the  number of VLIR chains,   and 253 characters because a sector
          holds 254 data bytes (2 bytes for the next track and sector link)
          and the last character must be a zero to terminate to text.
