Creating an infinite loop until an event occurs?

I am trying to make a loop until a certain event happens. In my first drafts I simply let it run for a large number of steps. However, now that I am adding a few extra steps in between, and want it to stop, it is no longer viable. Before I could run

N=100 for t=1:N (calculations) End

Which would do the loop 100 times. However, now I want it to continue forever until a certain event occurs. So now I am getting to:

N=10000 for t=1:N (calculations)

if (calculations) End % and finish here completely and do not engage in any more loops

Else (more calculations) End % and this should repeat back to the ‘for’ statement

Is there any way I can have this loop continuing, and block it in the middle after a certain event? Otherwise, is there another way of doing it?

    go = true;
  while go

    step1
    step2 
    step3
     if step3==stopcriteria
      go=false
     end

   end

Or

while true
    step1
    step2
    step3
    if step3==stopcriteria; break; end
end

Sorry it took a while to answer. I was playing with the code but it finally worked, and I thank you very much for your precise answers!

That just represents various lines of code. like what you want to do while in the "while true" loop
