C.6 Using Oracle CDD/Repository (OpenVMS)
C.6.2 Accessing Oracle CDD/Repository Definitions from Compaq COBOL
Programs
You access repository data definitions from a COBOL program using the COPY
FROM DICTIONARY statement. At compile time, the record definition and
its attributes are extracted from the designated repository. Then the compiler
converts the extracted definition into a COBOL declaration. For example, the
following COBOL statements access the customer and employee address records
defined earlier. These definitions have been placed in the repository directory
DEVICE:[VMS_DIRECTORY]SALES.
IDENTIFICATION DIVISION.
PROGRAM-ID. MASTER-FILE.
DATA DIVISION.
WORKING-STORAGE SECTION.
COPY "DEVICE:[VMS_DIRECTORY]SALES.CUSTOMER_ADDRESS_RECORD" FROM DICTIONARY.
COPY "DEVICE:[VMS_DIRECTORY]SALES.EMPLOYEE_ADDRESS_RECORD" FROM DICTIONARY.
.
.
.
If you compile this program with the /LIST and /COPY_LIST qualifiers, the
source listing includes the data definition translated into a COBOL declaration,
as shown in the following example:
1 IDENTIFICATION DIVISION.
2 PROGRAM-ID. MASTER-FILE.
3 DATA DIVISION.
4 WORKING-STORAGE SECTION.
5 COPY "DEVICE:[VMS_DIRECTORY]SALES.CUSTOMER_ADDRESS_RECORD" FROM DICTIONARY.

L 13 02 CITY PIC X(20).
L 14 02 STATE PIC X(2).
L 15 02 ZIP PIC X(5).
