Need Help??

This works, too:

@{${$another[0]}}[$i]

I think ist is a little bit clearer (from in to out): 1. fetch array element 0, 2. dereference, 3. treat it like an array, 4. fetch via [$i].

But this all looks really ugly. It would be better to fix the strange assignment to @another than to use such a complicated expression just to fetch a value...

I find Perl's data structures very useful but often get into a tangle with them. The main reason I had a go at the OP's question was to see if I could fathom it out. I was so pleased when I actually got something to work I couldn't resist the urge to show off!

I must now confess that I dereferenced it in stages first using temps. This is what I usually do myself if only so that I can still understand it the following day.

++ to you for being helpful rather than trying to be clever. My bad!
