Hi Kat,
just a few of quick questions ...

** How, as a maintainer of the code above, can I be sure that process flow only
gets to the "restart:" label from either the statement immediately preceding it
or the 'goto' inside the loop? In other words, how can I be sure that there is
not another 'goto restart' elsewhere in the code?

** If I have to place another looping construct within the same scope as the one
above, what should I call the labels?

** Under what circumstanes might I have to rename the labels?
