Set the B switch for indexed sequential files open INPUT or I-O. Set
the B1 switch for indexed sequential files open INPUT. Setting either
of these switches permits a file to be sequentially read, even if
another process has records locked within that file.
A file status of "locked record" is returned when a locked record is
read when the B switch is set; a file status of "00" is returned when
a locked record is read when the B1 switch is set.
Note: This switch also affects relative and record sequential files
when your program is compiled with the CALLFH directive set.
