in reply to Array qw difference

... the same array isn't working in qw same like the first one above?

They're not the same. "ABCGE ABCGE" produces a single string consisting in two alpha sequences separated by a space. qw produces groups (update: i.e., a list of zero or more) of non-space characters.

Data::Dumper is core, so you should be able to see this for yourself.
