When the ACUCOBOL configuration setting V_INTERNAL_LOCKS is set to "0" (off, false, no), Vision tracks locks but does not enforce internal record or file locking. The FairCom RTG configuration setting <runitlockdetect>, which aims to simulate the V_INTERNAL_LOCKS, did not enforce record locks but still enforced file locks. This modification corrects the file locking behavior so that it is now possible, for example, to exclusively open a file twice from the same run unit.
