Greg…first of all you need to define whre you are going to render(DRAW())
you line ,you need a RastPort for a Screen or a Window . the Screen could be
CUSTOMSCREEN or the WBSCREEN after you decide where to render the pass the
following :
SetAPen(&Screen->RastPort,1);
SetDrMd(&Screen->Rastport,JAM1);
Move(&Screen->RastPort,0,0);
for (x=0;x<640;x+=4) {
Draw(&Screen->RastPort,x,199);
}
Remenber that before you do all this you have to have a screen struct and all
of the proper libraries view.h;display.h ….amd many more you also have to
open the INTUITION libraries and the GRAPHICS librarie,the examples in the
disk s) work. by the way do you have a developers tool kit or just manuals.
if you want more help call CBM 215 431 9100 and ask for the tech. support
line. dont panic or get upset i have spend entire weekends 30-40 hrs reading
graphics primitives commamds and the intuition manual not to metion learning
C on the go good luck… Eduardo-
