Content-Type: text/plain

For a loop, try something along the lines of

        x =0.125
        do y = 80 by 800 by 40;
                if goododd = x then
                        do;
                        newscore = y;
                        y = 800;
                        end
                x+x;
        end;

For a direct approach, try something like

        newscore = int(log2(goododd/0.125)+.01) * 40 + 80
