I think a reverse lookup table will do the job nicely. Thanks.

A whuh?

Sounds like just a simple list, again. As four or five answers in this thread have already said. What requirement prevents you from using the code that has been posted four or five times?

Do not construct a doubly linked list. People build those things because they don't have perlfunc:splice, so in Perl, it's almost always the wrong way to go.

What I currently have is a function using jdporter's code above (which he described as a lookup table) that will look up the previous or next filename. Is this the code you're talking about or am I missing something?
