            RdsWindow = allocrdswindow();
            RdsWindow->XMIN = -200;
            RdsWindow->YMIN = -200;
            RdsWindow->XMAX =  200;
            RdsWindow->YMAX =  200;
            RdsWindow->DX   =  4;
            RdsWindow->DY   =  4;
            RdsWindow->SIDE =  100;
            RdsWindow->SIZE =  RdsWindow->DX * RdsWindow->DY ;
            RdsWindow->WINTAB = allocrdswin( RdsWindow->SIZE );
