in reply to Selecting Ranges of 2-Dimensional Data

I know that PDL uses fancy reference slices for multidimensional numerical matrixes. I don't know if it can be used for non-numeric matrixes (which you example implies), or whether you could at least use PDL-like techniques.

update: PDL::Char is a likely candidate.

    Thanks! I'll look into PDL.

    I should have said, the strings will be variable length - many of them only a couple of characters long, but some column headers or annotations are hundreds of characters long.
