Yes, Goofy , it is correct. I simplified my answer to explain the word OC . France had a langage partition: the South of the country (Languedoc, Provence .. used OC for yes - pronounced O- and in the Northern part the yes was pronounced OIL ( that became OUI ).
The Languedoc, as you mentionned, is the southern part where the Oc is in use ( see wikipedia entry : http://en.wikipedia.org/wiki/Langues_d'o%C3%AFl)
