Its initial value at run time is undefined. The VALUE clause cannot be specified for any group item, or subordinate item, that is EXTERNAL.ĮXTERNAL data cannot be initialized. The name used for the data item cannot be used on another EXTERNAL item within the same program. Items subordinate to an EXTERNAL group item inherit the EXTERNAL property. You specify the EXTERNAL clause on the 01-level data description in the WORKING-STORAGE Section of the COBOL program. The Possible Targets for a Procedure PointerĬOBOL programs can share data items by using the EXTERNAL clause. You can set procedure-pointers to contain entry addresses (or pointers) to the following entry points.Īn alternate entry point in another COBOL program (as defined in an ENTRY statement). You can set a procedure-pointer data item by using format 6 of the SET statement. Procedure pointers are data items defined with the USAGE IS PROCEDURE-POINTER clause. The intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources. The function delivered in this version is based upon the enhancement requests from a specific group of users. We reserve the right to make changes without notice at any time.

When the source members are uploaded to a ZOS Mainframe from the Windows and Micro Focus environment the file extensions are dropped. In the Windows and Micro Focus environment the file names have file extensions. This zipped file may be downloaded from the SimoTime Web site. The source code, data sets and documentation are provided in a single zipped file called CALLAM01.ZIP. Provide an example of defining and sharing data between two COBOL programs using EXTERNAL Data Items.Īlternatives for sharing data between programs. Provide an example of a COBOL program calling another COBOL program using a procedure pointer. Provide an example of defining and sharing data between two COBOL programs using traditional WORKING-STORAGE and LINKAGE section data definitions. Provide an example of a COBOL program calling another COBOL program using traditional coding techniques. This suite of programs will provide the following.
Also included is a suite of programs that show the traditional method for calling programs and passing data items. A LINKAGE Section will not be required in the secondary COBOL program since the data will be accessed (or shared) using EXTERNAL Data Items. The procedure pointer will then be used to call a secondary COBOL program. A procedure pointer will be defined in a primary COBOL (or mainline) program.
