I think you've confused overriding record locks with overriding exclusive file
access.   There  is  no  FAB$VRRL  (at  least  not in the VMS 4.7 macro, C, or
FORTRAN libraries); however, there IS a RAB$VRRL which permits you to  read  a
record  even if it is currently locked.  To open a file that's been opened for
exclusive access would appear to take calls to the ACP/QIO interface.
