Pointers & External Data COBOL Examples |
| When technology complements business | Copyright © 1987-2010 SimoTime Enterprises All Rights Reserved |
This suite of programs will describe how to use procedure pointers and external data items. A procedure pointer will be defined in a primary COBOL (or mainline) program. The procedure pointer will then be used to call a secondary COBOL program. A LINKAGE Section will not be required in the secondary COBOL program since the data will be accessed (or shared) using EXTERNAL Data Items. Also included is a suite of programs that show the traditional method for calling programs and passing data items.
This suite of programs will provide the following.
| 1. | Provide an example of a COBOL program calling another COBOL program using traditional coding techniques. |
| 2. | Provide an example of defining and sharing data between two COBOL programs using traditional WORKING-STORAGE and LINKAGE section data definitions. |
| 3. | Provide an example of a COBOL program calling another COBOL program using a procedure pointer. |
| 4. | Provide an example of defining and sharing data between two COBOL programs using EXTERNAL Data Items. |
The calling COBOL programs will build an 80-byte data record that will be passed to the called programs that will write the record to a sequential file.
The source code, data sets and documentation are provided in a single zipped file called CALLAM01.ZIP. This zipped file may be downloaded from the SimoTime Web site. In the Windows and Micro Focus environment the file names have file extensions. When the source memebrs are uploaded to a ZOS Mainframe from the Windows and Micro Focus environment the file extensions are dropped.
Procedure pointers are data items defined with the USAGE IS PROCEDURE-POINTER clause. You can set a procedure-pointer data item by using format 6 of the SET statement. You can set procedure-pointers to contain entry addresses (or pointers) to the following entry points:.
| 1. | Another COBOL program |
| 2. | A program written in another language. |
| 3. | An alternate entry point in another COBOL program (as defined in an ENTRY statement). |
COBOL programs can share data items by using the EXTERNAL clause. You specify the EXTERNAL clause on the 01-level data description in the WORKING-STORAGE Section of the COBOL program. The following rules apply.
| 1. | Items subordinate to an EXTERNAL group item inherit the EXTERNAL property. |
| 2. | The name used for the data item cannot be used on another EXTERNAL item within the same program. |
| 3. | The VALUE clause cannot be specified for any group item, or subordinate item, that is EXTERNAL. |
| 4. | EXTERNAL data cannot be initialized. Its initial value at run time is undefined. |
Note: If the application requires that EXTERNAL data items be initialized they may be explicitly initialized in the main program.
A COBOL program within a run unit that has the same data description for the item as the program containing (or defining) the item may access and process the data item. For example, if program A had the following data description:
01 MY-EXTERNAL-ITEM PIC X(10) EXTERNAL.
Program B could access the data item by having the identical data description in its WORKING-STORAGE Section.
Note: If the EXTERNAL data items are not identical then Program B will fail at execution time.
This section describes by example a COBOL program that uses the traditional method of calling a second COBOL program by program name. Parameters are passed using data (or a pass area) that is defined in the WORKING-STORAGE section of the calling program and is referenced in the LINKAGE section of the called program.
The following (CALLUSC1.CBL) is the primary (or calling) COBOL program that uses a standard "CALL by Program Name" approach to do the call. The data items are defined in the WORKING-STORAGE Section of the calling program and are passed to the called program via a USING clause on the call statement. To ensure the data is defined identically in both programs a copy file (PASSUS80.CPY) is used to define the data.

The following (CALLPEC2.CBL) is the secondary (or called) COBOL program that receives control via a procedure pointer. Both programs use EXTERNAL Data Items to pass (or share) data items. To ensure the EXTERNAL Data is defined identically in both programs a copy file (PASSEX80.CPY) is used to define the data. This program is an I/O module that simply writes records to a record sequential file.

The purpose of this suite of programs is as follows.
| 1. | Provide an example of a COBOL program calling another COBOL program using traditional coding techniques. |
| 2. | Provide an example of defining and sharing data between two COBOL programs using traditional WORKING-STORAGE and LINKAGE section data definitions. |
| 3. | Provide an example of a COBOL program calling another COBOL program using a procedure pointer. |
| 4. | Provide an example of defining and sharing data between two COBOL programs using EXTERNAL Data Items. |
The calling COBOL programs will build an 80-byte data record that will be passed to the called programs that will write the record to a sequential file.
