On the "while" comment: are you (or were they) referring to the fact
that a while loop can be expressed as a loop/exit when/end loop
construction, or is there something about while loops that should be
avoided?  Isn't there a preference hierarchy from for loop to while
loop to loop?  I.e. use a for loop whenever possible, failing that a
while loop, and as a last resort a loop with an exit.  OK, and as a
last last resort use a goto.
