in reply to Array in Array

I'm not sure what you want (and I've no idea what you find 'spooky'), but does this do it for you? 
#!/usr/bin/perl

use strict;
use warnings;

use YAML;

my @accounts = ("A x1 B y1 C z1 D v1 E w1 F",
                "A x2 B y2 C zzz2 D v2 E w2 F",
                "A x3 B y3 C z3 D v3 E w3 F",
                "A x4 B y4 C z4 D v4 E wwww4 F",
                "A x5 B y5 C z5 D v5 E w5 F",
                "A x6 B y6 C z6 D v6 E    F");

my @fields = ("A", "B", "C", "D", "E");

no warnings 'misc';
my @accounts_2 = map {[@{{split}}{@fields}]} @accounts;

print Dump \@accounts_2;
__END__

Short explaination of the map line: Take each element of @accounts, split it on white space, make an anonymous hash out of the results, and take a hash slice of that, indexed on @fields. Create an anonymous array of the result of the slice.

    Abigail,
    Thanks for the help.
    I get 
    ARRAY(0x253a350)
ARRAY(0x2536024)
ARRAY(0x2532bb8)
ARRAY(0x248e328)
ARRAY(0x248c1d0)
ARRAY(0x2488e40)

    if I run : 
    sub tweezers_sub
{
my @accounts_2 = map {[@{{split}}{@fields}]} @accounts;
foreach $rec(@accounts_2) 
        {
        print  FH_temp ("$rec\n");
        } # Prints all array records to the output file

}

    That's what I call the "spooky stuff". :-)

      Your $rec variable is actually a reference to an array. You should dereference it, for example by writing my @rray = @$rec;, or, TIMTOWTDI: 
      #!/usr/bin/perl

use strict;
use warnings;

my @accounts = ("A x1 B y1 C z1 D v1 E w1 F",
                "A x2 B y2 C zzz2 D v2 E w2 F",
                "A x3 B y3 C z3 D v3 E w3 F",
                "A x4 B y4 C z4 D v4 E wwww4 F",
                "A x5 B y5 C z5 D v5 E w5 F",
                "A x6 B y6 C z6 D v6 E    F");

my @fields = ("A", "B", "C", "D", "E");

sub tweezers_sub {
   my @accounts_2 = map { [@{{/([A-Z])\s+([a-z]+\d|\s)/g}}{@fields} ] 
+} @accounts;
   for my $rec (@accounts_2) {
      print "'" . join("' - '", @$rec) . "'\n";
   } 
}

tweezers_sub;

      This uses a RegEx instead of a split, but you can still see how $rec is dereferenced by writing @$rec.
      Hope this helped.

      Update: Mixed up referencing and dereferencing. Fixed.

      That's what you are supposed to get - you are printing out a reference to an array. What did you expect to get?

        I was hoping on the content. Life is not simple for an apprentice. :-( ;-)
