   Let's not start this argument again. ;-)  But there is visible bias
in your question, which has to be rooted out before the answer is
obvious.  There are many situations in which if statements, for loops,
while loops, etc., are more structured than gotos.  So if you want to
write a well structured program you use them.  There are a few cases
where the best structure uses gotos.  In those cases, if you are
trying to write a well structured program, you use a goto--unless you
are molested by the goto gestapo.  In my personnal experience, these
have only occured in programs which implemented finite state machines.
(And even then the main FSM loop was implemented as a loop.  The gotos
were to deal with special cases such as the final state.)

    There are rather more cases where the goto is better than the
stuctures available in langauges not as rich as Ada.  In those cases
the best choice may be to change languages. ;-)
