Data Update Functions
These functions change the data in fields.
lrvtc.retrieve_messages1 and lrvtc.retrieve_row change data as a side effect of popping data from the first row. They change data by shifting data up by a row. lrvtc.rotate* functions move data from the top to the bottom of the table.
