The Repository Paragraph

The Repository paragraph allows specification of program-prototypes-names, function-prototype-names, class-names, delegate-names, enum-names, interface-names and property-names that may be used within the scope of this Environment Division. It also allows declaration of intrinsic-function-names that may be used without specifying the word FUNCTION.

General Format

Note: With the exception of function-specifier, references to the following specifiers can now be made without the need to specify them in the REPOSITORY paragraph, by using the TYPE external-type-name syntax . The specifiers are listed here for backward compatibility.

Directives

  1. In addition to the Compiler directives which provide flagging and modify the reserved word list, the following directives may impact either the syntax or the semantics described in this section.
    • REPOSITORY - Creates a repository file or requests that the program being compiled is checked against the repository file.
    • RDFPATH - specifies the location of the library for the repository files.
    • ACTUAL-PARAMS - specifies the parameters to be used in the creation of a class or interface from a parameterized class or interface
    Note: None of these directives are applicable to .NET COBOL.

Syntax Rules

General Rules

  1. Class-name-1 is the name of a class that may be used throughout the scope of the containing Environment Division.
  2. If the AS phrase is specified, literal-1, literal-2, literal-3, literal-5 or literal-6 is the name by which the class, interface, program, function or delegate respectively, is known to the operating environment. Literal-4 is the name known to the operating environment for a method that implements the named property. The AS phrase is required when the name of a class, interface, property, function or delegate does not follow the rules for formation of a user-defined word or when the name is case specific.
  3. Class-name-3 and interface-name-1 are actual parameters for the parameterized class referenced by class-name-2.
  4. Class-name-4 and interface-name-4 are actual parameters for the parameterized interface referenced by interface-name-3.
  5. If the EXPANDS phrase is specified in a class-specifier, a class class-name-1 is created from the parameterized class class-name-2. The number of parameters in the USING phrase of the EXPANDS phrase of the class-specifier must be the same as the number of parameters in the USING phrase of the CLASS-ID paragraph of class-name-2. The interface for class-name-1 is the interface specified for class-name-2 with the parameters of class-name-2 replaced by the parameters specified in the class-specifier.

    The class class-name-1 is created from the parameterized class class-name-2 by replacing each specification of the formal parameter by the corresponding actual parameter. This replacement is done after the processing of COPY and REPLACE statements.

  6. The compiler uses the information specified for class-name-1 together with the external repository to determine the details of the class that is to be used. The repository information for the class must be in a file whose name is the externalized name of the class with the extension rdf. If the RDFPATH directive is specified, the file must be in the specified directory; otherwise, the file must be in the local directory where the .int and .idy files will be created.
  7. Interface-name-2 is the name of an interface that may be used throughout the scope of the containing Environment Division.
  8. If the EXPANDS phrase is specified in an interface-specifier, an interface interface-name-2 is created from the parameterized interface interface-name-3. The number of parameters in the USING phrase of the EXPANDS phrase of the interface-specifier must be the same as the number of parameters in the USING phrase of the INTERFACE-ID paragraph of interface-name-3. The interface for interface-name-2 is the interface specified for interface-name-3 with the parameters of interface-name-3 replaced by the parameters specified in the interface-specifier.

    The interface interface-name-2 is created from the parameterized interface interface-name-3 by replacing each specification of the formal parameter by the corresponding actual parameter. This replacement is done after the processing of COPY and REPLACE statements.

  9. The compiler uses the information specified for interface-name-2 together with the external repository to determine the details of the interface that is to be used. The repository information for the interface must be in a file whose name is the externalized name of the interface with the extension rdf. If the RDFPATH directive is specified, the file must be in the specified directory; otherwise, the file must be in the local directory where the .int and .idy files will be created.
  10. Property-name-1 is the name of an object property that may be used throughout the scope of the containing Environment Division.
  11. Program-prototype-name-1 is the name of a program prototype that may be used throughout the scope of the containing Environment Division.
  12. NET Delegate-name-1 is the name of a delegate definition that may be used throughout the scope of the containing Environment Division.
  13. Format 2 of the function-specifier is documentary only.
  14. ENTMF If ALL is specified in the intrinsic format of the function-specifier, it is as if each of the intrinsic-function-names defined in the topic Intrinsic Functions were specified.
  15. ENTMF If ALL is specified, you shall not specify any intrinsic function name as a user-defined word, within the scope of this REPOSITORY paragraph.
  16. NETJVM Enum-name-1 is the name of an enumeration definition that may be used throughout the scope of the containing Environment Division.
  17. If a prototype definition or a program definition for program-prototype-name-1 is specified previously in this compilation group, that definition is used to determine the details for activating the program identified by program-prototoype-name-1. Otherwise, the external repository is used to determine the details for activating the program with the externalized name program-prototype-name-1 and that program is activated when program-prototype-name-1 is referenced.
  18. Function-prototype-name-1 is the name of a function prototype that may be used throughout the scope of the containing Environment Division.
  19. If a prototype definition or a function definition for function-prototype-name-1 is specified previously in this compilation group, that definition is used to determine the details for activating the function identified by function-prototoype-name-1. Otherwise, the external repository is used to determine the details for activating the function with the externalized name function-prototype-name-1 and that function is activated when function-prototype-name-1 is referenced.
