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

I got $5 that says this is homework. "must have subroutine used" is
a dead giveaway.

Agreed. Which is why he does not get any fish before showing his
attempts at fishing for himself ;-)
