I'm having difficulty parsing your question to figure out what you're
asking, but I think what you're looking for is the ref() function,
which returns a true value if given a reference (actually, it returns
a string representing what type of reference it's given: 'ARRAY',
'HASH', 'CODE', 'SCALAR', etc), and returns a false value if given a
non-reference.
ref([EMAIL PROTECTED]) ==> 'ARRAY'
ref(\$foo) ==> 'SCALAR'
ref(\%foo) ==> 'HASH'
ref("foo") ==> ''
perldoc -f ref
