DICTDDF (Dictionary Definition File)
DICTDDF (Dictionary Definition File)
DICTDDF (Dictionary Definition File) is an unstructured file that contains one DDF
record with the next object number to be assigned, the next text ID number to be
assigned, the DDL compiler product version information, and the creator’s user ID. The
DDF record is updated every time the DDL compiler adds a new object to the
dictionary. DICTDDF cannot be an audited file.
DICTDDF is different on G-series and H-series systems—see:
•
Figure D-3, DICTDDF (Dictionary Definition File)—G-Series, on page D-7
•
Figure D-4, DICTDDF (Dictionary Definition File)—H-Series, on page D-7
Change bars in Figure D-4
on page D-7 show where it differs from Figure D-3 on
page D-7.
Table D-3, DICTDDF (Dictionary Definition File) Fields, on page D-8, applies to both
G-series and H-series systems.

Field Description
OBJECT-NUMBER The object number of this record from DICTODF.OBJECT.
The record in DICTODF contains the constant name and its
object-type code, “CD.”
TEXT-ID The text ID assigned to the constant; it is used to link the
constant record to the record for this constant in DICTOTF.
CONSTANT-TYPE-STRING A two-character ASCII code that identifies the type of the
constant.
CONSTANT-TYPE A numeric code identifying the type of the constant.
CONSTANT-TYPE-EXPLICIT Contains an ASCII character Y (yes) to indicate the constant
type was entered explicitly or N (no) to indicate the constant
type was inherited from another constant or by default.
