It seems like you were just missing the split step.

split ' ' would be better (and be just like qw)

Hi,

You can use splice also to achieve this.

          my @array= qw(A R N D);
          splice(@array,0,4,qw(B N M C));

any suggestions?

I, too, may not really understand your question, but:

c:\@Work\Perl\monks>perl -wMstrict -MData::Dump -le
"my @array = qw(A R N D);
 dd \@array;
 ;;
 @array = 'B N M C' =~ m{ \S }xmsg;
 dd \@array;
 ;;
 @array = 'Be No More Care' =~ m{ \S }xmsg;
 dd \@array;
 ;;
 @array = 'Be No More Care' =~ m{ [[:upper:]] }xmsg;
 dd \@array;
 ;;
 @array = 'Be No More Care' =~ m{ \S+ }xmsg;
 dd \@array;
"
["A", "R", "N", "D"]

["B", "N", "M", "C"]

["B", "e", "N", "o", "M", "o", "r", "e", "C", "a", "r", "e"]

["B", "N", "M", "C"]

["Be", "No", "More", "Care"]

Note that the pattern you use is really important!

The previous answers were pretty good but in case you are still confused here you go:

my @array = qw(A R N D);
# is equivalent to
my @array = ();
$array[0] = 'A';
$array[1] = 'R';
$array[2] = 'N';
$array[3] = 'D';

So it should be obvious to you how you can overwrite any part of the array...simply reference it by its index:

$array[0] = 'B';
