I would like to write a perl script with the following criteria match.

Give it a shot. Then post any questions you might encounter (please read
the posting guidelines first).

1. open any text file taken the name from the command line.
2. read top 20 lines and stops, then
3. ask to press letter "n or p" (for next/previous) to print next or
previous 20 lines.
would appreciate any kind of help.
4. must have subroutine used.

Look up $. in perldoc perlvar
