Why is it that the first two splits do not produce any elements?
#!/usr/local/bin/perl
use strict;

my $var = 100421;
my @elems1 = split(/\d/,$var);
my @elems2 = split(/./,$var);
my @elems3 = split(//,$var);
split discards the pattern split on. To keep it, place it in parentheses.
my @elems = split( /(\d)/, $var );
See `perldoc -f split` http://perldoc.perl.org/functions/split.html

I like Perl; it's the only language where you can bless your
thingy.
Eliminate software piracy: use only FLOSS.
