This example shows how to use COMMIT to make a data definition
    permanent:

    RDO> DEFINE DATABASE 'INVENTORY'.
    RDO> SHOW DATABASES
    Database with db_handle INVENTORY in file INVENTORY
    RDO> DEFINE FIELD PART DATATYPE TEXT SIZE 10.
    RDO> DEFINE RELATION TEST.
    cont> PART.
    cont> END TEST RELATION.
    RDO>
    RDO> COMMIT
    RDO> SHOW RELATIONS
    User Relations in Database with db_handle INVENTORY
            TEST
    RDO> SHOW FIELDS
    User Fields in Database with db_handle INVENTORY
         PART                             text size is  10
    RDO> EXIT

    This example shows how to define a database, a field, and a
    relation. These statements would normally be in an indirect
    command file. After you define the database and its components,
    the COMMIT statement makes the database permanent. If you do not
    issue the COMMIT statement, RDO returns this message:

    There are uncommitted changes to a database or the data
    dictionary Would you like a chance to COMMIT these changes [NO]?
