           Version 3.1 Notes -- K. M. Schultz  -- 01/07/87
           -----------------------------------------------

Version 3.1 modifications are as follows:

    - Removed graphics characters so terminals not supporting VT-100 codes
      could be used.

    - Added a library containing a compiled version.  The compiled version
      in ROLDEX31.LBR can be installed for most popular terminals using the
      GINST program.  It will run on any CPM machine with a Z80 and 48k TPA.

    - The current menu choice can now be changed several ways.  You can use
      ctrl-s and ctrl-d to go backward and forward through the choices
      or you can use the TAB key or SPACE bar to determine your menu choice.
      As in the version 3.0, RETURN activates your choice.

    - Since I couldn't get v3.0 to compile (let alone run) on my system with
      48.5k TPA, the code was restructured to make overlays.  A significant
      reduction in variable space was realized by using a global data record
      rather than local data records in several procedures.  The flow of menus
      was changed slightly to get enough code into overlays.  Making labels
      was moved from the UPDATE menu to the main SELECT menu where it more
      logically belongs.

    - The code for the DEC dot matrix printer was modified to use OKIDATA
      ML92/93 codes.  The compiled version can be patched for any printer
      which used 6 bytes or less to set the pitch.
