}REAL multi-level arrays?

Define "REAL".  Real as in you can write $a[$j][$i] = something and have it
work "naturally".  Not real in that the elements aren't contiguous in
memory  (but then neither are Perl 1-d arrays).  If you want "real" multi-d
arrays, for certain definitions of "real", and you're running under Unix,
look into the PDL module, which is designed for just this problem.

}Eh?  What page of the book is
}this on?  I'd like to read up on this!  This isn't the
}"fake out Perl" stuff is it?  :-?

Page 257-265 of the second edition Camel.
