This sounds like an xy+problem. You have expressed some ideas about how to achieve something without detail on WHAT you are trying to achieve.

for Lookups, a hash would be a much better structure. Are you trying to come up with some sort of encryption scheme ?

A few pointers:
* @words would probably work better as %words (a hash).
* When you do I/O using <>, you most likely need a "chomp"
* If @numbers2 contains 0..40K in random order, why not sort it, so it is indexed easier ?
Alternatively, create an index array that indirectly accesses @numbers2.

In any case .. let us know what you want to build, and I'm sure you will get many helpful suggestions, and perhaps, even code.

        This is not an optical illusion, it just looks like one.
