COBRT041 Corrupt index file (Recoverable) Your run-time system does not recognize the control information for an indexed file and as the index has been corrupted in
some way the data in the file is no longer accessible by your system. This error is recoverable in the sense that it can be
trapped but should you receive it, you can do little except to close any open files and stop your program's run.
COBRT043 File information missing for indexed file (Fatal) The most likely reason for this error is that the names of either the data part or the index part of the file are not consistent
with the setting of the IDXNAMETYPE FIle Handler configuration option.
COBRT047 Indexed structure overflow (Fatal) The structure of your indexed file contains a fault. You have probably tried to put another entry in the index when there
is no room for it. This may be because you have reached the maximum number of duplicate keys.
