Script that can Copy a Range of files from Tape to Hard disk

Hi:

I am a trying to write a script using a loop i guess. What I need to do is write a script that can allow my users to load a tape and copy a range of files from a tape to the hard disk. By range I mean, I would like the users to pick a range of numbers like files 3 - 8 and the script will copy files 3 - 8 from the tape to the hard disk. Please help. I have succesfully allowed the users to pick 1 file but can't get this range to work. Thanks in advance. Oh by the way we are using Korn....

Please see attachement for the script...

I do not know how to do the loop..
