I didn't even spot the change in field numbers in the OP! If that is a real criterium:
my $csv = Text::CSV_XS->new ({ binary => 1, auto_diag => 1});
my @hdr;
while (my $row = $csv->getline ($fh)) {
# example:
if ( # a change in number of columns
@hdr != @$row
or
# first column matches header criterium
$row->[0] =~ m/^[A-Z]/
) {
@hdr = @{$row};
next;
}
# just an example
my %hash;
@hash{@hdr} = @$row;
}
Enjoy, Have FUN! H.Merijn
