It is used for populating the part numbers hash. The part number is the key and '1' is the associated value. The '1' doesn't matter. You just want to have a hash with part numbers as the unique keys of the hash since you can quickly and easily check to see if a key exists in a hash. For example:
print "$key exists in hash" if exists $hash{$key};
