444,Mr,Edge
$ cat stack.pl
use warnings;
use strict;

die qq[Usage: perl $0 file1 file2\n] if @ARGV != 2;

my ( %code );

while ( <> ) {
        chomp;
        my @f = split /,/, $_, 2;
        next if @f != 2;
        push @{ $code{ $f[0] } }, $f[1];
}

for ( sort keys %code ) {
        printf qq[%d,%s\n],
                $_,
                join ",", @{ $code{ $_ } };
