In all 3 of your examples, you don't show us the declaration of your
variables nor how they are filled with data. I can make some
assumptions, though.

If I assume that the @datas variable is declared like this:
my @datas = qw( One Two Three Four Five Six Seven );
then I can take a slice of that array to initiate the next array:
my @indatas = @datas[0 .. 4];
I think in Example 1, you just need to reference the @datas array with
an '@' sign at the front (instead of a '$' sign) when you are using it
to create a slice.
> Example 2:
> $nkey = $dataln[3] . $dataln[4];
If I assume that the @dataln variable is declared like this:
my @dataln = qw( A B C D E F G H );
then I can easily create a scalar variable, $nkey, by concatanating
two of the elements of the @dataln array:
my $nkey = $dataln[3] . $dataln[4];
It looks to me that you got this one right. Is this what you were
asking?
> Example 3:
> $base{$bv[0]} = [ $bv[1], $bv[2], $bv[3], $bv[4] ];
If I assume that the @bv array and the %base hash are declared like
this:
my @bv = qw( Alpha Bravo Charlie Delta Echo );
my %base;
then I can initiate an element of that hash with a slice from the @bv
array:
$base{$bv[0]} = [EMAIL PROTECTED] .. 4]];
Again, when taking a slice from an array, you need to reference the
array with the '@' sign. Your example works, but you asked for
simpler/easier ways to do things.
Were these examples helpful? Maybe if you gave us a better idea of
what you wanted to do with what kind of data we could be more specific
helping you.
