Subject: Re: indices of non nil elements in an array

Thanks.  I tried that and realized that I lost all of the information
about the indices in so doing.  As I've thought about this some more
and have realized that the index of the non-nil elements is just as
important to me as the non-nil elements themselves, I've decided that
using a Hash is probably a better solution to my needs than using an
Array.
