Write your own modules.Build your libaries. That is what code re-use all about it.

If you really have problems with opening/closing files, you need little practice. May be your mind is faster on 'what' part rather than 'how' part. But there is some Perl which is essential and you should atleast read "Learning Perl" or any other basic Perl book as a refresher.

You can write all your essential code in one script use that as a template if you think template is way to go.
