DICTOBL (Object Build List)
DICTOBL (Object Build List)
DICTOBL (Object Build List) is a key-sequenced file that contains one record for each
element of each unique object in the dictionary. The primary key of the file is the
OBJECT field from DICTODF plus a sequentially assigned element number.
An object can contain one or more elements.
If an object or an element within an object is defined by a TYPE * or TYPE def-name
clause, elements of the referenced object are copied to each DICTOBL field for the
referring object. The top-level SOURCE-DEF field in this file contains the object
number of the referenced definition.
If a record's structure is defined by a DEFINITION IS def-name clause, DICTOBL
has no entry for the referenced object. Instead, linkage is made through DICTRDF
(Record Definition File). DICTRDF.DEF-NUMBER contains the object number of the
referenced definition. For all other records, DICTRDF.DEF-NUMBER contains the
object number of the record itself.
DICTOBL is different on G-series and H-series systems—see:
•
Figure D-9, DICTOBL (Object Build List)—G-Series, on page D-16
•
Figure D-10, DICTOBL (Object Build List)—H-Series, on page D-21
Change bars in Figure D-10 on page D-21 show where it differs from Figure D-9 on
page D-16.
These tables apply to both G-series and H-series systems:
