  Given a pointer to a lores screen, how can I read a pallete number
from the screen without using the linea routines but with pointer
manipulation?  Can I just write:

    char Color_Number, *Screen;
    int x,y;

    Color_Number = Screen[x/2 + 160*y];

then manipulate the byte to get the pallete number? If possible
please send some example C source code to my email address:

    bferrer@bonnie.ics.uci.edu

thanks....

In a state of confusion,


Bill Ferrer
