Course Objectives

Perl is a mature, extremely flexible, general-purpose language, which is especially well suited to textual manipulation. In addition to its extensive built-in facilities, there are vast freely-accessible libraries of Perl code to help build almost every conceivable application.

This course builds on the techniques in Perl Programming - Part 1. It covers the more advanced programming and data structuring techniques provided by Perl, including references, modules and object-oriented techniques, suitable for high-level applications of all types.
