Perl5 and Advanced Perl4 Features

Given by Geoffrey C. Fox,Nancy McCracken,Tom Scavo at Computational Science for Information Age Course CPS616 on Sept 20 97. Foils prepared Sept 20 97

See Perl Home Page http://www.perl.com/ for background information and resources such as manual!
This foilset mainly extends the previous Perl Overview with a discussion of some key Perl5 capabilities. However, some topics may be advanced Perl4 features
We give an initial summary of Perl5 changes and then discuss:
Some old and new functions in Perl
Regular expression enhancements
New syntax, especially -> and =>
New subroutine calling and declaration syntax
Hard (address) and soft (symbol table) references
General data structures, including multidimensional arrays
Object-oriented features: packages, classes, and methods

Table of Contents for Perl5 and Advanced Perl4 Features

There are two types of foils -- html and image which are each available in basic and JavaScript enabled "focused" style
(basic:)(focus style:) Denote Foils where Image has important information
(basic:)(focus style:) Denote Foils where HTML is sufficient
