Each module is used differently. Almost all modules can be included in your
program with the statement (usually near the beginning of your program):
use Module;
where you substitute the name of the module you are going to use for "Module".
This statement imports the module's program statements into your program. This
happens at compile time, no matter where in your program you actually put the
'use' statement.
You can also import modules using 'do' or 'require', but you need to know what
those do and why to use them before you use them instead of 'use'.
Modules come in two flavors: procedural and object-oriented. Some modules
support both flavors. Most modules come with built-in documentation that
describes how to use them, usually including some sample code statements. To
access the documentation, you can do the following on a command-line:
perldoc Module
Strawberry Perl may afford another way of accessing documentation.
Procedural modules will import functions into your namespace, so you can just
call these functions as if they were part of built-in Perl or part of your own
program.
Object-oriented modules allow you to create "objects" of the module class, and
call methods of those objects. To create an object instance of the Module class:
my $object = Module->new();
The new() method is a convention. It could be called anything, but most OO
modules use a new() method for object creation, Some new() methods take
arguments.
To call a method on the object:
$object->method();
See the documentation for each module to find out what functions and methods
are available.
There are Perl tutorials for using modules and doing object-oriented
programming:
perldoc perlmod
perldoc perlmodlib
perldoc perlmodstyle
perldoc perlmodinstall
perldoc perlboot
perldoc perltoot
perldoc perltooc
Good luck!
