Hello steve,
what seems to be your immediate problem is that you are trying to do the
following:
$foo[0] = @bar;
$foo[1] = @baz;
and so on...
that does not work in perl; you can only assign scalars to arrays and
hashes, (for the details behind this, i'll refer you to
www.sharemation.com/~perl/tut where some basic tutorials explain a few
things) and you are assigning arrays to @foo.
ok, so what to do? the answer is not so complicated thankfully....
$foo[0] = \@bar; #store a reference to @bar in @foo (for more details,
see the above link again)
now you can access this array again as follow:
@quux = @{$foo[0]} # dereference again by putting an @ in front
of the reference
as for the substring part, you might want to concider using regexes instead,
since they'll be a bit more friendly to possible changes on the site where
you 're getting your info from (if well written), but i'll leave that up to
you =)
hope this helps,
