Examples
What follows are examples of "Hello, World" implemented in different styles of modules. It must be understood that a module is not necessary in Perl; functions and code can be defined and used anywhere. This is just for example purposes. Contrast with Java where a class is always necessary. A real "Hello, World" function would be written like so:
sub hello { "Hello, world!\n" } print hello;or simply printed in one line:
print "Hello, world!\n";Read more about this topic: Perl Modules
