Hi, Aia.
Yes, I noted that. His title was What is the meaning the $ special character?
He also asked ...explain to me how it's categorized and it's extract [sic] definition?
He did not restrict the meaning to any special instance.
I appreciate that he used Google, but I think he may not have had enough time to internalize the information. I know that I don't always understand something just after I read it.
For example from the Wikipedia article: In most shell scripting languages, $ is used for interpolating environment variables, special variables ... -- it seems hard to imagine an alternate definition.
Thanks for the comment, it's always useful to have feedback and more than one set of dispassionate eyes looking over things ... cheers, drl

www::wikipedia::entry
WWW::Wikipedia::Entry(3pm) User Contributed Perl Documentation WWW::Wikipedia::Entry(3pm)
NAME
WWW::Wikipedia::Entry - A class for representing a Wikipedia Entry
SYNOPSIS
my $wiki = WWW::Wikipedia->new();
my $entry = $wiki->search( 'Perl' );
print $entry->text();
my $entry_es = $entry->language( 'es' );
print $entry_es->text();
DESCRIPTION
WWW::Wikipedia::Entry objects are usually created using the search() method on a WWW::Wikipedia object to search for a term. Once you've
got an entry object you can then extract pieces of information from the entry using the following methods.
METHODS
new()
You probably won't use this one, it's the constructor that is called behind the scenes with the correct arguments by
WWW::Wikipedia::search().
text()
The brief text for the entry. This will provide the first paragraph of text; basically everything up to the first heading. Ordinarily this
will be what you want to use. When there doesn't appear to be summary text you will be returned the fulltext instead.
If text() returns nothing then you probably are looking at a disambiguation entry, and should use related() to lookup more specific
entries.
text_basic()
The same as "text()", but not run through Text::Autoformat.
fulltext()
Returns the full text for the entry, which can be extensive.
fulltext_basic()
The same as "fulltext()", but not run through Text::Autoformat.
title()
Returns a title of the entry.
related()
Returns a list of terms in the wikipedia that are mentioned in the entry text.
categories()
Returns a list of categories which the entry is part of. So Perl is part of the Programming languages category.
headings()
Returns a list of headings used in the entry.
raw()
Returns the raw wikitext for the entry.
language()
With no parameters, it will return the current language of the entry. By specifying a two-letter language code, it will return the same
entry in that language, if available.
languages()
Returns an array of two letter language codes denoting the languages in which this entry is available.
