Object Oriented Perl - First Steps

For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.

There are some occasions when a new example that I write / a topic that comes up on a course results in an article that's so long that it doesn't fit into the Blog / short article format, but requires a more substantial mechanism.

And so it is for my First steps in Object Oriented Perl examples, written yesterday and taking you through how you can hold all the data about multiple things ("objects") of a type ("class") in a hash, and then access the data easily in it through Perl subs ("methods"). The example then went on to show you how you can define slightly different types of things and keep them all in the same list, with the program working out at run time which particular piece of code to run ("polymorphism") with the detailed logic or how to deal with the data hidden with ("encapsulated") the file that describes the class ("package / module").

So I'm just giving you a taster here (see the previous paragraph) and I have provided a longer article on Perl - First Object Steps in our separate Solutions Centre
