Effects of Restrictor Parameters

If all the keys of the access path to which a RTVOBJ function attaches are supplied as restrictor parameters, only the record with the given key or keys is read.

If none of the keys for the access path are supplied as restrictor parameters, all of the records in the access path are read.
