GrandFather -

No worries there. I asked for an array of arrays, and that's what you gave me. I was just wanting to clarify that the method of accessing them would be as I posted earlier

$records[firstarray][firstrecord]
$records[secondarray][firstrecord]
.
.
[download]

I'll work on sorting it out and post back if I have problems.

Regards,
Scott

That looks backwards to me. In fact I'd code access as:

for my $record (@records) {
    for my $line (@$record) {
        ....
    }
}
[download]

$records[firstrecord][firstarray] could also be written $records[firstrecord]->[firstarray] to emphasise that @records is an array of references to arrays. Keep in mind that Perl only allows scalar values for arrays and hashes, but a reference to something (like and array) is a scalar.

True laziness is hard work
