MATLAB: While Loops- Flaps Problem, need advice

Question

I have a program that sets the flaps on an airplane(Theoretically) up and down 5 degrees each time, but when i get to 30 is should only display Flaps Full DOWN, and when it gets to 0 is should be Flaps Full UP and shouldnt display the degrees. Is there a function that will get me out of the elseif statemnt? because break; gets me out of the whole program. Heres my program:

%Glass cockpit flap simulator:

total=0;

cnt=0;

again = true;

while again==true

    let=lower(input('U for up, D for down, Q for quit:','s'));
    cnt=cnt+1;
    if let~='u' && let~='d' && let~= 'q'
        fprintf('Please enter a valid response!\n')
    elseif let=='u' && total>0
        total=total-5;
        if total==0
            fprintf('Flaps Full UP')
        end
        fprintf('Flaps at %g degrees\n',total)
    elseif let=='d' && total<30
        total=total+5;
        if total==30
            fprintf('Flaps Full DOWN')
        end
        fprintf('Flaps at %g degrees\n',total)
    elseif let=='q'
        fprintf('Thanks for testing your flaps design!\n')
        again=false;
    elseif total== 30
        fprintf('Flaps Full DOWN\n')
    elseif total==0
        fprintf('Flaps Full UP\n')
    end
end

Answer 1

 If total >= 30
   %flaps full down
 end
