I agree that there is more than one good way to do everything. Gerhard's code is fine. For a loop where it is invariant, I should prefer to save and reuse n'&array; and I prefer the boolean assignment statement and AIF
|&elements_exhausted setb (&i gt &ne) | aif (&elements_exhausted).traversal_lend to his single statement. I even object, but not much, to |.trvend anop , I supply the missing-operand comma for anop, mexit, etc., only when I want to place a comment after it. These, however, are details that are important only as they contribute to coherence.
