Turns set-processing messages on and off.
SET MEMBERCOUNT ON|OFF
When MEMBERCOUNT is set ON, messages tracking the progress of set-processing commands are output. Messages overwrite each other at intervals specified by the SET MEMBERINTERVAL command.
Progress messages take the form nnn processed. Messages are output with a carriage return but with no line feed; therefore, successive messages are written to the same screen position.
The printing of progress messages can slow execution slightly.
