Re: goto's, and loops

Hi all,
  If I remember right the only place to use a goto would be in an error
trapping routine where you would not want the routine to return back to the
next line after the error but instead break out and give an user error then
quit.  Other than that I cannot think of any structured modern day
programming language that promotes the use of goto's.  I would say that its
better programming practice to stay away from the goto keyword for both the
programmer writing the program and for others that are trying to figure out
what that programmer did.  As far as the loops go the only difference
between a while-do and repeat-until is one is pessimistic and the other is
optimistic.  I don't really think that this would matter one way or the
other, I guess it depends on how you think. That's my 2 cents

Thanks,
JKinsey

Here is Euphoria's repeat-until loop

while not <expression> do
end while

Isn't it nice that a single construct can be used
for more than 1 job.  I always thought that BASIC's
do_until loop was redundant.
