Lock a specific record in the data server for exclusive write access.
<oArrayServer>:RLock([<iRecNo>]) Æ lSuccess
|<iRecNo>||Number of the record, which is to be locked. As default the current record number is used.|
|lSuccess||Logical value, which indicates whether the record could be locked.|
|TRUE||The record could be locked.|
|FALSE||The record could not be locked.|
bArrayServer:RLock() does not really lock the record but merely returns the value TRUE. The method is implemented only as a compatibility measure with DBServer classes.
