I would never qualify as a structure purest, but I see a huge
difference between these. There is no guarentee that a GOTO will
simply bypass a section of code and the TAG will appear somewhere
shortly after the GOTO. A LEAVE or ITER is confined to the immediate
DO loop and is easy see the affect (because we always use ENDDO
and not END).

The SELECT/WHEN/OTHER/ENDSL has allowed me to greatly reduce
the amount of complicated nesting in my code. This is where I used to
use GOTO and TAG alot. I will break the structured rules where nesting
causes a program to become difficult to read. The ITER and LEAVE
has also helped. I veiw the ITER and LEAVE as a controlled GOTO that
is easy to follow.
