Summary: 



  I am trying to re-assign ConoutPtr using MSDOS Turbo Pascal. In this way, I 
should be able to use my own console output driver. I was able to do this 
easily in Z80 Turbo Pascal as follows:

   ConOutPtr := Addr( MyOutputRoutine );

  where MyOutputRoutine is a previously defined procedure.
 This does not work with the MSDOS version since the addressing schemes are
different. I thought I would be able to do it like this:

    ConOutPtr := Ptr( Cseg, Ofs( MyOutputRoutine ) );

  but this gave me a compile time type mismatch.  The Z80 way of doing it gives
a syntax error.  Anyone know how to do this??  Thanks.
