All, Thanks for the responses. Yeah, the idea of using a hash had crossed my mind. I'm not very proficient with them, but it did occur to me that it might be the way to go in this situation. However, I should have mentioned in the original post that there will cases where fields will be mapped to the same new field name, i.e.: 
if ($field eq unvLocalPhone) || ($field eq unvCampusPhone)){
     $field = "Phone";
}

There will several or more cases of this actually. I am wondering if these instances make using a hash a bit more cumbersome?

Performance is an issue with this script; it is already a bit slow due to the size of the directory being searched. I have read on more than one occasion that hashes, while good coding practice in Perl, are somewhat more resource intensive than simple arrays. Though in this case all of these conditionals may negate any theoretical performance gain achieved by using a simple array. Any thoughts here?

Thanks again.
