PERL Part II - Beyond The Basics
Course: PP2BTB
Duration: 4 Days
Level: II
Course Summary
PERL Part 2 – BEYOND THE BASICS builds on the techniques
in Perl Part 1 – Basics, and covers some of the
more advanced programming and data structuring techniques
provided by Perl and suitable for high-level applications
of all types.
Upon completion, delegates will be able to use advanced
Perl features of references, modules, and object-oriented
techniques.
This highly-practical course discusses further Perl programming
in the Windows and Red Hat Linux environments, although
the course is applicable to other platforms.

Who Should Take This Course
This course is valuable for programmers, technical managers,
and system and network administrators familiar with basic
Perl.
Recommended Prerequisites
Delegates should have solid familiarity with basic Perl,
including scalar, list, and hash array literals and variables
and common operations on them; control structures and
related operators; file operations; and subroutines, including
the use of my and local variables. This may be achieved
by completing our Perl Part 1 – Basics course.
