Note! This site is about Perl 6.
If you are looking for a solution for the current production version of Perl 5, please check out
the Perl 5 tutorial.
Strings can be stored in so called scalar variables.
Each such variable starts with a $ sign and then alphanumeric characters, underscore or dash.
Before using such a variable the first time one has to declare it by the my keyword.
Variables are case sensitive.
my $greeting = "Hello World";
my $Gábor-was-born-in = 'Hungary';
By default scalar variables have no specific types but later we will see how
can we restrict the values a scalar can hold to a number or to any other type.
One can also declare a variable without giving it an inital value:
In such case the value of the variable will be Any() which
is just case of being not defined.
The Perl 6 Tricks and Treats newsletter has been around for a while.
If you are interested to get special notification when there is new content
on this site, it is the best way to keep track:
This is a newsletter temporarily running on my personal site (szabgab.com) using Mailman,
till I implement an alternative system in Perl 6.
