53: The language interface version is invalid

An application tried to access a file containing variable-length

records with a language interface from Btrieve v3.15 or earlier.

54: The variable-length portion of the record is corrupt

During a Get or Step operation, the MicroKernel could not read all

or part of the variable-length portion of a record. The MicroKernel

returns as much data as possible to the application. This status code

usually indicates that one or more pages used to store variable-length

records are corrupt. Check the data buffer length the MicroKernel

returns to see how much of the record was returned. Recover the

damaged file as described in Pervasive PSQL User's Guide.

55: The application specified an invalid attribute for an

AUTOINCREMENT key

The data field indexed by an AUTOINCREMENT key can be part of

a different segmented key only if the key number of the

AUTOINCREMENT key is less than the key number of the new

segmented key and the new data type flag referencing the field is not

AUTOINCREMENT

56: An index is incomplete

An index can be damaged if a Create Index operation (31) or a Drop

Index operation (32) is interrupted before it runs to completion.

Perform a Drop Index operation to completely remove the damaged

index from the file, then rebuild the index with the Create Index

operation, if desired.

57: An expanded memory error occurred

This status code is obsolete in MicroKernel versions 6.0 and later.

Btrieve for DOS returns this status code if it receives an error from

the Expanded Memory Manager. This status code usually means that

the MicroKernel was unable to save or restore the memory mapping

application that uses expanded memory.
