First, you should read Perl's object documentation. perldoc perlobj perldoc perltoot Those two, at the very least, will help. >Blessed variables A scalar that has been bless()ed to a specific [class]. See [object]. >Class methods A [method] that is expected to be invoked by the name of a [class], rather than by an [object]. Example: my $query = CGI->new; That calls the new() method of the CGI class; 'CGI' is the first argument to the function. >Classes A [package] that is expected to be used in an object-oriented manner. It should have (or inherit) a constructor and some other methods. >Functions See [subroutine]. >Global variables See [package variable]. Can also mean one of the "true" global variables, such as @ARGV, which always refers to the same variable, no matter what [package] you are in. >Instance methods A [method] expected to be invoked by an [object]. Example: @entries = $query->param; Here, the $query [object] calls the param [method]; the first argument to method() is $query. >Methods A fancy name for a [function] that is expected to be used in an object- oriented manner. >Objects A "thingy". Really. It's a variable that "belongs" to a [class]. >Package variables A variable that belongs to a specific [package]. The default [package] for any program is 'main', so $foo is really $main::foo, where 'main' is the [package] and '::' is the package-variable separator. The variable $File::Find::name is $name in the 'File::Find' [package]. >Packages A namespace in Perl, denoted by the 'package' keyword. package Game::TicTacToe; >Subroutines A storable chunk of code that can be invoked multiple times. >Is there a simple yet comprehensive explanation out there with an example of >each? Didn't think so. Anyone want to take the time to explain it? Sounds like you could stand some reading of the fine manual. -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ ** Look for "Regular Expressions in Perl" published by Manning, in 2002 ** <stu> what does y/// stand for? <tenderpuss> why, yansliterate of course. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
