C.6 Using Oracle CDD/Repository (OpenVMS)
• A relationship between the MASTER_FILE object and the EMPLOYEE_
ADDRESS_RECORD definition
In addition, the record definitions are included in the compiled module.
The COPY FROM DICTIONARY statement is used when you want to create a
relationship between a compiled module and a record or field definition. The
RECORD statement is used when you need to create a relationship between a
compiled module and some other kind of repository object — one that you do not
want copied into the compiled module. For example, suppose you need to create
a relationship between the MASTER_FILE compiled module object and a text file
object, such as a functional specification. This relationship would indicate that
the compiled module is derived from the functional specification. For example:
IDENTIFICATION DIVISION.
PROGRAM-ID. MASTER-FILE.
.
.
.
PROCEDURE DIVISION.
A0100.
.
.
.
RECORD DEPENDENCY "DEVICE:[VMS_DIRECTORY]SALES.SPECIFICATION"
TYPE IS "CDD$COMPILED_DERIVED_FROM" IN DICTIONARY.
.
.
.
When this program is compiled with the /DEPENDENCY_DATA qualifier, the
compiler creates the following objects and relationships:
• A compiled module object called MASTER_FILE
• A temporary file object representing the object file produced by the
compilation
• A relationship between the MASTER_FILE compiled module object and the
object file
• A relationship between the MASTER_FILE object and the repository object
called SPECIFICATION, which represents the functional specification text
file
For more information on the RECORD statement, refer to the Compaq COBOL
Reference Manual. For more information on the /DEPENDENCY_DATA qualifier,
invoke the online HELP facility for COBOL at the operating system prompt.
C.6.4 Data Types
Oracle CDD/Repository supports some data types that are not native to Compaq
COBOL. If a data definition contains a field declared with an unsupported data
type, Compaq COBOL issues a fatal diagnostic. The Compaq COBOL compiler
does not attempt to approximate a data type that it does not support.
Table C–1 shows how Oracle CDD/Repository data types are translated into
COBOL data types. It also states the level of support Compaq COBOL provides
for Oracle CDD/Repository data types.
