Do you mean something like this?

% Step A
while( true )
    % Step B
    % Step C
    % Step D
    if( condition )
        continue  % <-- return to Step B
    end
    % Step E
    break  % <-- go to Step F
end
% Step F

Without more details about your code, it is hard to know what logic you really need.
