Blocking is irrelivant. The concept of a record integrated into the
OS kernel is mandatory. You don't lock a block...unless your MS
trying to market your single user Access data file system as a multi-
user database.
See prevoius message about lock manager, distributed lock manager,
distributed transaction manager, and clustering.
