SHOW USE OF Statement

an open DDL dictionary.
SHOW USE OF { [ DEF[INITION] ] def-name [,] ...}
constant-name
is the name of a constant in the open DDL dictionary. You can specify up to 50
constants.
def-name
is a DDL name that uniquely identifies a definition in an open DDL dictionary. You
can specify up to 50 definitions.

functions as if the specified object is a definition. Such action provides compatibility
with previous versions of DDL.
type-name
is a DDL name that uniquely identifies a token type defined in an open DDL
dictionary. You can specify up to 50 token types.
