Get or set a property which tells the engine whether or not to use automatic persistence. AutoPersist is true by default. AutoPersist saves out all cells with values which do not have formulas in them. If AutoPersist is false, only cells marked as "zCPersist" in Excel are persisted.
See the User Guide for more information on marking Excel cells as zCPersist.
