It is not clear how you are getting your data but if you hold the column names in a separate array from the data you can use List::MoreUtils->mesh() to combine the two, joining each element with the delimiter \x01.

johngg@shiraz:~/perl/Monks$ perl -Mstrict -Mwarnings -MList::MoreUtils
+=mesh -E '
my $delim   = qq{\x01};
my @colHdrs = qw{ Name Sex Age Job };
my @data    = (
   [ qw{ Fred M 27 Janitor } ],
   [ qw{ Mary F 31 Researcher } ],
   );
my $outFile = q{spw11101656.out};
open my $outFH, q{>}, $outFile
   or die qq{open: > $outFile: $!\n};
foreach my $raDataLine ( @data )
{
    say $outFH join $delim, mesh @colHdrs, @{ $raDataLine };
}
close $outFH
   or die qq{close: > $outFile: $!\n};'
johngg@shiraz:~/perl/Monks$ hexdump -C spw11101656.out
