Well, for one thing, both files are being opened for "read only" access ("<"). "+<" will allow both read and write.
You might consider reading the first file's code - room pairs into a hash (presuming that each numeric code is unique) and open the second file substituting the hash key for the hash value "looked up" in the first file.
