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.

The C Language references include the information on the C# and the Java functions.
