Does @{ $hash{$k} } work as a reference? What does @{} do?

What does @{} do? It dereferences the array. See also: perlref perlreftut References quick reference	[reply]

Ah, okay. Then this explains why the array did not work in my case. I need to dereference it as to work on it. Thanks for the links, I'll check them out now. I guess a good knowledge of using references in Perl would help me solve many of my problems.	[reply]
