Learning Perl - whether you're new to programming or 'converting'.
This course covers programming in the Perl language.
Whether you'll be using Perl for data manipulation tasks, administration
scripts, or web interaction, you should start here.
The first sections of this course introduce you gently to computer
programming, using practical examples in the Perl language and
leads on to writing some simple application programs so that you
can see how the elements all slot together.
The core of the course introduces further fundamental parts of Perl.
You'll learn about topics such as: regular expressions, lists,
subroutines and hashes, and you'll be taught how to use them
together in both traditional (keyboard and screen) and Web server-based work.
The course concludes with sections on resources that are available,
and a forward-looking lecture that overviews many more of the
facilities available in Perl, and what they can do for you.
Basic computer knowledge.
Getting the most from your Well House Consultants course
Perl is a very widely used programming language indeed, but it's
name isn't well know outside the programming community as it's an open
source language that lack the marketing "hype" - it's just a superb
technical tool in a very wide variety of applications. It's name - PERL -
stands for the "Practical Extraction and Reporting language" which is
a pretty good sound-bite to tell you what it does.
A new release
of Perl - Perl 6 - has been undergoing development for a considerable time.
Our course covers Perl 5, and will continue to do so while it is dominant,
but also includes a short look ahead to Perl 6 so that new code developers
will be able to take advantage of it once it's available to them.
