MFS Locking for Single User (None Specified)

We have a situation where we would like to lock records in a secondary file whenever the primary record is locked, and unlock them again whenever that primary record is unlocked. The best place to do this, it would seem, is within an MFS that traps LOCK.RECORD, UNLOCK.RECORD, and UNLOCK.ALL calls.
However, these calls are not made to the MFS for a single user system. This results in the primary record being locked internally but the secondary records are not locked at all and can be accessed by other parts of the system. It would seem a better answer would be to trap the RTP Lock and Unlock calls, but this is not possible because I think RTP36 is encoded into the bootstrap and can't be shelled.
Is there any way this task can be achieved without trying to do it at the application level (which would not be easy to implement) ?.
Thanks,
Henry

Henry,
As you noted, if the network bit is not set then the file system is not requested to do the lock.
The reason the network bit is not set is because you have an older OENGINE.RUN … even if it has been upgraded to a recent version, it kept the setting of the network bit.
If you info@revelation.com me your engine (ATTN: Cameron) I can verify this and quickly resolve the problem.
