You can just go ahead and read two lines. Eg:
my $line1 = <FH>;
my $line2 = <FH>;
If you need to go back in the file for some reason, you could use tell
and seek to save the file position and return to it. It's probably easier
to just set a flag that says you have lines saved or maybe write a sub to
read lines ahead for you and return current or +n line.
Your question is poorly stated in that it requires the reader to make all
sorts of assumptions on what you mean and what you are trying to do.
