If I put in a line that says

print "$diary_data[0]\n";

it prints:

ARRAY(0x3bfda0)

If I change the print slightly, like this:

print "@{$diary_data[0]}\n";

This is what I get:

HASH(0x3bfdc4)

Then if I try

print "%{$diary_data[0]}\n";

it gives me:

%{ARRAY(0x3bfdd0)}

I don't think I'm understanding this correctly. The first example looks to me like a scalar reference, pulling data out of an array; but since the array contains hashes, then how does this get pulled out? Is this "ARRAY(0x3bfda0)" line an internal reference to how Perl remembers something?

Anyway, I'm off to read perldsc for a while.

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
