Reading a list of data into a function using a script.

Well, i’ve been a ksh geek for only prob 2 years now, but my job requires the managing of HUGE amounts of files and data (usually about 6500 files/items per query,set). Managing and querying such large amounts of data by hand is impossible and just a waste of time when you can have a ksh script do this for you! This recipe is just an example of what you can do with some variables, menus, and functions!
