Table of Contents Previous Section Next Section Introduction

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.
  Alternatives for sharing data between programs.

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 members are uploaded to a ZOS Mainframe from the Windows and Micro Focus environment the file extensions are dropped.


We have made a significant effort to ensure the documents and software technologies are correct and accurate. We reserve the right to make changes without notice at any time. The function delivered in this version is based upon the enhancement requests from a specific group of users. The intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources.

Table of Contents Previous Section Next Section Procedure Pointer

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).
  The Possible Targets for a Procedure Pointer

Table of Contents Previous Section Next Section External Data

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.
  Rules for External Data

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.

Table of Contents Previous Section Next Section CALL, Program Name & LINKAGE

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.

Table of Contents Previous Section Next Section Primary COBOL 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 (CALLUSC2.cbl) is the secondary (or called) COBOL program that receives control via a traditional call by name. 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. The data items are then accessed based on the data definitions of the called program's LINKAGE Section. To ensure the data is defined identically in both programs a copy file (PASSUS80.cpy) is used to define the data. This called program is an I/O module that simply writes records to a record sequential file.

Table of Contents Previous Section Next Section CALL, Pointer & External Data

This section describes by example a COBOL program that uses a procedure pointer to call a second COBOL program. Data is passed (or shared) by both programs using EXTERNAL Data Items that are defined in the WORKING-STORAGE Section of each program. A LINKAGE Section is not required in the called program.

Table of Contents Previous Section Next Section Primary COBOL Program

The following (CALLPEC1.cbl) is the primary (or calling) COBOL program that uses a procedure pointer to do the call. 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.

Table of Contents Previous Section Next Section Called COBOL Routine, an I/O Module

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.

Table of Contents Previous Section Next Section Company Overview

SimoTime Technologies was founded in 1987 and is a privately owned company. We specialize in the creation and deployment of business applications using new or existing technologies and services. We have a team of individuals that understand the broad range of technologies being used in today's environments. Our customers include small businesses using Internet technologies to corporations using very large mainframe systems.

Quite often, to reach larger markets or provide a higher level of service to existing customers it requires the newer Internet technologies to work in a complementary manner with existing corporate mainframe systems. We specialize in preparing applications and the associated data that are currently residing on a single platform to be distributed across a variety of platforms.

Preparing the application programs will require the transfer of source members that will be compiled and deployed on the target platform. The data will need to be transferred between the systems and may need to be converted and validated at various stages within the process. SimoTime has the technology, services and experience to assist in the application and data management tasks involved with doing business in a multi-system environment.

Whether you want to use the Internet to expand into new market segments or as a delivery vehicle for existing business functions or need assistance with converting non-relational data structures simply give us a call at 415 883-6565 or check the web site at http://www.simotime.com
