B, B1 run-time switches

Properties:

Default: Off
Type: File handling

Comments:

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 in 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.
