Perl Introduction

This Introduction to Perl gets you started with the basics of programming in the Perl environment. We cover the very basics through to the beginning of modular coding in your own programs to enable ease of maintenance and readability.

ON COMPLETION

  • Understand the Perl environment and syntax
  • Create useable scripts
  • Understand some of the weird syntax and expressions
  • Work with files and other processes
  • Use simple data structures
  • Make decisions and flow control

WHO SHOULD ATTEND?

New comers to programming or those wanting to know where to start.

COURSE WORK

The course work is based around a 50/50 approach to lecture and hands on giving the attendee the chance to really work with the language and see its potential. The practical work is based around real life scenarios as much as possible and is intended to make the delegate feel more at easy with working with the language and boost their confidence about working it. It will also give you lots of example code to use in existing projects.

PRE-REQUISITS

None, although if you have done any programming with a structured language before you will be at an advantage.
