 Either the application tried to open a v5.x data file that was

previously accessed in Accelerated mode by a v5.x MicroKernel

and never successfully closed, or the application tried to open a

file for which a v6.0 or later MicroKernel encountered an

unrecoverable error during a Set or Clear Owner operation. The

file integrity cannot be ensured. Refer to Advanced Operations

Guide for information about recovering damaged files.

 Your application tried to open a file in MicroKernel v5.x format

using a v5.x MicroKernel; however, that same file was previously

accessed by a v6.0 or later MicroKernel, which failed to close the

file successfully and left a pre-image file on the disk. Version 5.x

MicroKernels cannot read pre-image files created in v6.0 or later

format.

43: The specified record address is invalid

The MicroKernel returns this status code for the following reasons:

 The record address specified for a Get Direct operation is invalid.

Either the address is outside the file boundaries, or it is not on a

record boundary within or on a data page, or the record at the

specified address has been deleted. For a Get Direct operation,

specify the 4-byte address obtained by a Get Position operation.

 If the records’ file is in v5.x format, this status code can indicate

a file access conflict. For example, task 1 has a file locked in an

exclusive transaction. Task 2 is reading records from the same file

and tries to update a record that the transaction inserted. If task

2 reads the record and then task 1 aborts the transaction, task 2

receives this status code when issuing the Update operation.

 For a Find Percentage operation that is seeking a percentage

based on a record’s physical location within the file, the specified

record address is invalid.

 The file may be corrupt, and you must recover it. Refer to

Advanced Operations Guide for information about recovering

damaged files.

44: The specified key path is invalid

The application tried to use the Get Direct/Record operation to

establish positioning on an index path for a key whose value is null

in the corresponding record. The MicroKernel cannot establish

positioning based on a null key value.
