Hi, Documentation says it is available in PERL 5. 22.
http://perldoc.perl.org/Hash/Util.html Is it a documentation mistake? Tamas -----Ursprüngliche Nachricht----- Von: Kent Fredric [mailto:kentfred...@gmail.com] Gesendet: Mittwoch, 8.

Most likely explanation: Your code was written for Perl >5.18, where those functions were available, but you're running it on a perl before <5.18, where those functions don't exist yet. "qw" is a quote operator for lists of words. For instance: my (@array) = qw( hello world ); Has the same effect as if you'd written: my (@array) = split " ", q[ hello world ]; or my (@array) = split " ", "hello world"; or my (@array) = ('hello', 'world'); Obviously it is much easier to write than the last example, and is impervious to accidentally typing trailing spaces inside the quotes: my (@array) = ('hello', 'world '); # Hope you see the space! -- Kent KENTNL - https://metacpan.org/author/KENTNL
