Perl arrays are indexed starting at zero (0) so the eighth word in an
array would be i

Actually it was "[split /\s+/]->[8]" not "split[/\s+/]->[8]", and you only
need to do it like that if you are using it in a "print" statement (I
couldn't get it to work otherwise). Otherwise you can use the method Nikola
explained or using the method you use below (the one that works).

try
$abc = ( split /\s+/ )[8];
you can use the parenth with any function that returns an array, and just
pop a [] on the end.
FYI if you want the last element (not knowing what place it's in) just use
[$#_]
This only works if you are not using @_ (or $_ I think). Use caution
for [$#_].
