Actually, I've been a basic programmer for a longer time that C-programmer.
I ain't
against basic. But it is quite crappy for anything except scripting (beats
perl
in nicest syntax)

Goto has it's uses. But is crap now with functions.

It's only a matter of opinion. You probably already know the argument. Goto
usually makes code less readable. Not necesserely, of course. And yeah,
then there's this sport in not using a goto anywhere :)
In this case, using a return() had an advantage as well; The code should be
in a function to make reuse possible. And then a return() can make a goto
end;'s
work.
