Looping though a numerically indexed array

[Bob Sneidar]

Ditto, and I am not sure what noticeable impact one method would have over another. There was some blurb a long time ago about how these keys are internally sorted. I believe what was proposed is that a set of NUMERIC keys beginning with 0 would actually sort correctly.
