Tic and Toc question

Hi everyone, I just have a quick question. How would I numerate my tic and toc so that I can make my program stop after a certain amount of time? I'm trying to say like, while tic<1 (second), continue, but I am most likely doing it wrong. Can anyone help?

end

tStart = tic;
for n=1:2000
    n
    if toc(tStart)>=0.1   %100 miliseconds
        disp('time exceeded')
        break    %if it's a function use return
    end
end
