Euler,
I hope you don't mind me publishing your question in the Eu forum.

Why not? I would not like to break any existing code so loop labels would have
to be optional. Also,
any loop could have a label. I suspect that the loop identifier should only be
scoped to the
containing routine (or file if its not in a routine). Though it might be argued
that the scope
should only be to the identifier loop and nested loops, similar to the automatic
index variable in
FOR loops.

  for i = 1 to width do:bAcross
     . . .
     for j = 1 to Height do:bDown
        . . .
        if a then exit bAcross end if
        . . .
        while c do:bAnalysis
            . . . 
            if b then exit bDown end if
            if d then exit bAcross end if
            . . .
        end bAnalysis
        . . .
     end bDown
     . . . 
  end bAcross
