Here is code from Escape from Zol, 4341 hex offset subroutine

Not much to say, but look at the HTML output.

void DrawBorderTile(int Arg_acc) {
Global135 = Arg_acc;
usub_4313();
LLocal1 = 7;
do {
        *GUI_Draw_Pointer[LLocal1] = *Global18[LLocal1];
        LLocal1 = (LLocal1 - 1);
} while (LLocal1 >= 0);//LoopEndWh 434D
*Redraw_PointerToColourMap[0] = BorderDrawParamColour;
return();// 4355
};
