DICTKDF (Key Definition File)
When a record is declared with a DEFINITION IS clause, DICTOBL has no entry for
the new record. Instead, the data structure is found in DICTOBL by looking up the
referenced definition number in DICTRDF.
DICTKDF (Key Definition File)
DICTKDF contains one record for each primary key and each alternate key, or each
SEQUENCE IS field declared for each record in the dictionary. DICTKDF records are
uniquely identified by the object number of the record that contains the key and an
element number.
For the sample dictionary shown in Example D-4 on page D-64, the fields of DICTKDF
have these values.
