RELATION statement:
o Refer to an existing global field by name. This includes the
global definition in the relation.
o Refer to a new global field name and include a complete
definition, including a DATATYPE clause. This includes the
field definition in the relation and also enters the field
definition in the global set of definitions for the database.
o Refer to an existing global field in a BASED ON clause. This
