TVDEMO, a Turbo Vision example from Borland Pascal

  In order for the original source code from Borland to work with
  Virtual Pascal for OS/2, the following changes need to me made.  Note,
  that the source will still work with Borland Pascal after the changes
  have been made.

  * Add Use32 to all the Uses clause of all units

  * Change TVDEMO.PAS:
    - Change line 230 from
        MaxHeapSize := HeapSize;
      to
        {$IFNDEF VirtualPascal} MaxHeapSize := HeapSize; {$ENDIF}

  * Change CALENDAR.PAS and PUZZLE.PAS:
    Since the Word type is 32 bit in Virtual Pascal, the declaration on
    line 142 (CALENDAR.PAR) or line 117 (PUZZLE.PAS):
      B: array[0..Width] of Word;
    should be changed to
      B: TDrawBuffer;
    The tDrawBuffer explicitly uses a 16-bit Word type and is compatible
    with both Virtual Pascal and Borland Pascal.

  * Change TVDEMO.PAS:
    - After the Uses clause, add the following:

        {$IFDEF VPDEMO}
          {$Dynamic VP11Demo.Lib}
        {$ENDIF}

      This means, that the program will use all units stored in the
      Demo Licence DLL (vp11demo.dll) when the program is compiled with
      the demonstration version of VP/2.
