The normal (Perlish, elegant) way of doing list references would be as follows:
# Save our place.
push @stack, [$i, $curlvl, \@thisBOM];
...
# Now, recover where we left off.
($i, $curlvl, $raBOM) = @{pop @stack};
...
print $i: @{$raBOM-[$i]}\n;
I believe it has the added bonus of not copying

you handle the hierarchical nature of the relationship. perhaps a

Guys,
This script:

push @array, [$_:, 1, 2, 3];

for (0..$#array) {

Thanks to all those who helped, so far! :-)
foreach ( @array ) {
print join ( , , @{$_} ), \n;
}
This is the nice easy print statement I was looking for, but I don't quite understand
it. I get the print, and the join, but what is @{$_} all about?
Going back to the array:
1/1/2004 0 34.5
use strict;
use warnings;
my @array;
for (0..3) {
push @array, [$_:, 1, 2, 3];
}
for my $R (@array) {
print join(,, @$R) , \n;
# for (0..3) {
# my $col = $_;
# print $array[$row][$col], unless ($col == 3);
# print
b) find out how big it is (easily)
c) have in interpolated
all using the dereferencing syntax.

@{$_} dereferences the array reference created with []. For instance,
my $ref = [1,2,3];
is the same as
my @arr = (1,2,3);
my $ref = [EMAIL PROTECTED];
To access the array (1,2,3) using $ref, you need to say @{$ref} or, to
access an individual element of it, you can say $ref-[0], $ref-[1],
Gives:
0:, 1, 2, 3
1:, 1, 2, 3
2:, 1, 2, 3
3:, 1, 2, 3
Which is what I'd expect, and is designed to put the data
into a csv file.
First, is this the best way to do it, or is there a neater trick?
This is a neat trick:
use Template;
my $template = Template-new || die
