How to convert this code without 'goto' statement?

Since goto statement is not valid in matlab, how can I use the following code written in embedded matlab function:

function y = fcn(clk, lfsr)

jump :

upperT=1000;

count=1;

T=666;

y=1;

label :

if clk==1

    Ton=0.806*T;

    if Ton<T

        y=1;

    if count<Ton

        count=count+1;

        goto label;

    elseif Ton<count<T

        y=0;

        count=count+1;

        goto label;

    elseif count>T 

    count=1;

    T=lfsr+upperT;

    goto label;

    else

        goto jump;

    end

    else

        goto jump;

    end

else

    goto jump;

end

end

That is code you wouldn't want to use. As it stands the function has no way to exit. Regardless of the results of all the 'if', 'elseif' and 'else' conditions, it would always jump back to either "label" or "jump".

Be assured that valid code (which this isn't) can always be transformed so that it would avoid having to do a 'goto', though in some cases it might become somewhat more complicated. Actually this code can be revised so as to avoid goto's but I prefer not to waste time on it because of its erroneous nature.
