Is q{first} == 'first' Yes, see perlop. Why use it? I find it easier to parse than ' and have adopted braces as delimiters and tend to stick to them. ymmv. In this case though `$hash{first}` works find (no need for either).	[reply] [d/l]

But are you really 'storing' the arrays in that hash...or just the a reference to those arrays? If I undef array1 and array2..will I still have values in my hash? Or if I tie the Hash to a DB file. Will the file contain the contents of each of the arrays...or just the array references?	[reply]

Only scalars can be hash values (see perlref). Therefore, you cannot "store an array" into a hash. You can only store the reference.	[reply]
