The famous "GRAPH.H" Lib

Hello,

  I've got the source code of a program, written in 1992 to control the
values of an industry machine, and I need to recompile it again but,
unfortunatly, I haven't got the original Microsoft C compiler that was
used to.

  When I tried to recompile with my actual Visual C++ (nmake and the
makefiles), an error appears because I need the graph.h librery to draw
in MsDos.

 As I can see on the Internet, none've got it. Can anybody take me a
hand? 

 Thanks a lot.
