CORE:: just means to use the core unlink (builtin version). This is useful if you have overridden the core unlink and want to get back to it rather than your overridden version. So if you had a sub 'unlink' in your module, but you wanted to call the builtin version instead, you could do so by using the CORE:: package prefix. > By the way,I find reading the Perl Source Code is very interesting and > can get a lot of knowledge,But for me,It has some difficulties > sometimes,I need lookup many books when I meet a question.So can you > recommand some Groups or News Groups which research it specially.Then > when I have some problems I could ask about it! Try combining all the core pods into a single man page and then you can search it for things you are looking for. Sample program to do it is on my Tripod site 'perlman.pl'. I never refer to books when I'm coding - everything I need is in the man pages and code that I've previously written or snarfed from these lists. -- ,-/- __ _ _ $Bill Luebkert Mailto:[EMAIL PROTECTED] (_/ / ) // // DBE Collectibles Mailto:[EMAIL PROTECTED] / ) /--< o // // Castle of Medieval Myth & Magic http://www.todbe.com/ -/-' /___/_<_</_</_ http://dbecoll.tripod.com/ (My Perl/Lakers stuff) _______________________________________________ ActivePerl mailing list [email protected] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
