in reply to Join returning array reference, not string... why?

You want to print @{$files[(($ii-1)/3)]{map1}} rather than $files[(($ii-1)/3)]{map1} since the latter is a reference to a list and the former converts it to a list the join function expects.

Hope this helps, -gjb-

    Yeah, that was one of those bracketed things that I tried, and what that did was return the array, but join only used the scalar context and printed: 
    map : [4]

    ... that's part of why I got so puzzled. Thanks, though!
