Completely correct of course. I have no idea why I didn't think of that
one. I tend to go out of my way whenever possible to create
non-assiciative arrays when I can, for the reason I illistrated.
Perhaps it's a bad habit, but it has served me well in the past under
certain circumstances. I think this is why associative arrays
completely slipped my mind.

Thanks for clearing that up, and my humble apologies for any confusion
caused to the OP.

All the best.
