I am making my first attempt at porting a DOS program written with MSC that
included graph.h to DJGPP  2.03 using GRX 2.4.3.

In the original program I have

   _setvideomoderows(_VRES16COLOR, _MAXTEXTROWS);

With GRX in grx20.h there are several structs for different video modes, and
there is a function prototype that reads

int GrSetMode(GrGraphicsMode which, ...);

Is this what I should use? If so, what should the value of which be? The
program is originally written for 16 color, and the boss is hoping to
upgrade to 256 color.

Thank you,

jdk
