Perl module P251
Perl Review
Exercises, examples and other material relating to training module P251. This topic is presented on public courses Using Perl on the Web, Perl for Larger Projects, Perl Extra

Everyone who attends a typical advanced training course has a different background. Typically, they'll be strong in most of the fundamentals but may have a few niggling questions or aspects that they're about weak on. This module fast-tracks through the fundamentals of Perl. During presentation, the tutor will take time to cover in a little more depth any subjects that warrant such extra coverage for the group of students on the particular course.

2242So what is this thing called Perl that I keep harping on about?
"An overview of the Perl Language" It almost sound like one of those dreaded school essays that I had to write in my several attempts to get an English "O" level (they were the things that came before GCSEs) ... but these days I enjoy writing.
