RLOCK()
 Changed behaviour
──────────────────────────────────────────────────────────────────────────────────

 RLOCK() now does the same thing as DBUNLOCKALL(), DBRLOCK(RECNO())

 You should no longer test on IF RLOCK() after an APPEND, as problems
 may occur:

 APPEND BLANK         // Appends a locked record

 IF RLOCK()           // Here, the record is unlocked, then locked again.
    ...               // If another workstation suddenly locked the record
 ENDIF                // on a fast server, you'd get in trouble.


 Instead, check the DBRLOCKLIST() for the desired RECNO(), or use NETERR()
