Don't use the term "symlink", however tempting, or you'll confuse yourself and others about real symlinks. Yes, it's not an array in the hash; it's a scalar containing a *reference* to an array, and there may or may not be other references to that array elsewhere in the program depending on how the reference was constructed (with the anonymous arrayref constructor or with the reference to a named array). -- Peter Scott http://www.perlmedic.com/ http://www.perldebugged.com/ -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
