Agreed.  I've been into discussions on this several times, and stand firm on
the principle I've gotten into many debates on before.  Fact remains, if you
know what your doing, you can code *ANYTHING* without having to "break" out
of a loop, or "GOTO" a label, etc.  The school I attended taught
"Logic" in a 
class before teaching any programming language.  Flowcharting was learned,
and you was to write all your programs on a flow chart first.  This helped
you create programs that had 1 starting point and 1 ending point with no
nasty goto's, break's etc...  Granted, its something you can't exactly do
with Windows and all those **** call-backs, events, handlers, etc.  But...
Any pascal for loop can be re-done as a repeat/until, and while others may
not see the simplicity, it shows exactly what the compiler is generating....
Eg.

        FOR Dummy := 1 TO 5 DO BEGIN
           If You = 3 Then Dummy := 4;
           IF Me = 2 Then Dummy := 5;
           IF Me = You Then Dummy := 1;
           IF Me > You Then Inc(Dummy);
         END;

As
          Dummy := 1;
          REPEAT
            IF (You = 3) Then Dummy := 4;
            IF (Me = 2) Then Dummy := 5;
            IF (Me = You) Then Dummy := 1;
            IF (Me > You) Then Inc(Dummy);
            Inc(Dummy)
           UNTIL (Dummy > 5);

On the 2nd, to me its clearer when Dummy gets initialized, when Dummy is incre
mented, and When /how the loop repeats its self....
