81: The MicroKernel encountered a lock error

The MicroKernel returns this status code in one of the following

situations:

 The application tried to unlock a record that is locked with a

multiple record lock, but the record position stored in the data

buffer does not correspond to any record locked in the

associated file.

 The application tried to unlock a single-record lock with a

multiple-record lock or vice-versa.

82: The MicroKernel lost positioning

When performing a Get Next or Get Previous operation on a key

with duplicates, the application tried to retrieve a record that was

deleted or whose key value was modified by another application. Use

a Get Equal or a Get Direct/Record operation to re-establish

positioning. (See Status Code 44: The specified key path is invalid

for a related positioning problem.)

83: The MicroKernel attempted to update or delete a

record that was read outside the transaction

This status code is obsolete in MicroKernel versions 7.0 and later.

The application tried to update or delete a record within a

transaction, but it did not read the record within the transaction.

The application must read the record within the transaction before

attempting to modify the data.

84: The record or page is locked

 An Insert, Update, or Delete operation attempted to lock an

index page to insert or delete a key value. Have your application

check for this status code and retry the operation if the status

code is returned.

 The application tried one of the following:

 Applied a no-wait lock on a record that is currently locked

by another application

 Tried to access a file in a no-wait transaction while another

application holds one or more active record locks in that file
