COBOL Program calls COBOL Routine

VSAM, COBOL I/O Routine COBOL Program calls COBOL Routine |

| The SimoTime Home Page |
Introduction
This suite of programs provides an example of how a mainline COBOL program calls a COBOL I/O routine to access a VSAM data set. Both COBOL programs are written using the VS COBOL II dialect and should work with COBOL for MVS and COBOL/370. A JCL member is provided to run the job as an MVS batch job on an IBM mainframe or as a project with Micro Focus Mainframe Express (MFE) running on a PC with Windows.
This program may serve as a tutorial for programmers that are new to COBOL, JCL or VSAM and as a reference for experienced programmers.
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.

The Calling Convention
The following summarizes the items needed for a "caller program" (CBLCBLC1.cbl) to call a "called program" (CBLCBLC2.CBL).
The "caller program" needs the following data structure (PASS-AREA) to be defined in the WORKING-STORAGE section.
WORKING-STORAGE SECTION.
*****************************************************************
* Data Structure used for calling CBLCBLC2.
* The CALL statement is as follows…
* CALL 'CBLCBLC2' USING PASS-AREA
*
01 PASS-AREA.
05 PASS-REQUEST pic X(8).
05 PASS-RESULT pic S9(9) comp.
88 NORMAL-RESULT value 0.
88 COBOL-RESULT-SAME value 8.
88 EOF-RESULT value 16.
05 PASS-RECORD.
10 PASS-KEY pic X(6).
10 PASS-INFO pic X(74).
The "caller program" contains the following statement in the PROCEDURE DIVISION to make the call to the "called program".
CALL 'CBLCBLC2' USING PASS-AREA
The "called-program" needs the following Linkage Section defined for the pass area.
LINKAGE SECTION.
*****************************************************************
* Data Structure used for passing a data string.
* The Procedure Division statement must also be as follows…
* The PROCEDURE DIVISION using PASS-AREA.
*
01 PASS-AREA.
05 PASS-REQUEST pic X(8).
05 PASS-RESULT pic S9(9) comp.
88 NORMAL-RESULT value 0.
88 COBOL-RESULT-SAME value 8.
88 EOF-RESULT value 16.
05 PASS-RECORD.
10 PASS-KEY pic X(6).
10 PASS-INFO pic X(74).
In addition to defining the pass area in the Linkage Section the "called program" needs the Procedure Division statement to be coded as follows.
PROCEDURE DIVISION using PASS-AREA.
The source code listings for both the "caller program" and the "called program" are included within this document.
The JCL Members
This suite of six (6) JCL members will provide the capability of creating a sequential file, defining a cluster for a KSDS, updating the KSDS with the data in the sequential file and then execute the COBOL calling COBOL to access and display the records in the KSDS. The two other JCL members are provided to delete the files.

The following sub-sections will describe the preceding JCL Members in more detail.
Execute COBOL calling COBOL
The following is the mainframe JCL (CBLCBLJ1.jcl) required to run the mainline program. The coding technique is used with the expectation the JCL would be used as a stand alone procedure. The job and DD statements will need to be modified for different mainframe environments.

//* Subject: JCL to delete a VSAM Data Set using the IDCAMS Utility *
//* Author: SimoTime Technologies *
//* Date: January 1, 1998 *
//*-------------------------------------------------------------------*
//* The following example is more than what is usually required to *
//* delete a VSAM Data Set. However, the purpose is to illustrate the *
//* functions of the IDCAMS utility. *
//* PURGE: A VSAM Data Set may be date-protected. The DEFINE Cluster *
//* has the option of specifying a retention date. If this *
//* retention date has not expired then the PURGE option will *
//* be required in order to delete the data set. *
//* The default is NOPURGE. *
//* ERASE: The standard operation by the VSAM DELETE is to delete *
//* the catalog entry of the cluster and mark the space used *
//* by the cluster as reclaimable. The data contents of the *
//* cluster is no longer generally available but it is still *
//* present until the area is reused. This introduces a *
//* potential problem or security exposure for sensitive data.*
//* The information could be retrieved using some special *
//* class of DUMP/RESTORE utilities that are often used by *
//* data center staff. The ERASE function will write over the *
//* data area used by the cluster and the original data is *
//* destroyed. The default is NOERASE. *

rem * This set of programs illustrates the use a COBOL program

rem *
rem * The COBOL program is compiled with the ASSIGN(EXTERNAL) directive.
rem * This provides for external file mapping of the file names.
rem *
rem * This set of programs will run on a Personal Computer with Windows
rem * and Micro Focus Net Express.

The Mainline COBOL Program
This program (CBLCBLC1.cbl) was written to be used as a teaching and learning aid. The displays are not required and the parameters use full words. The displays would probably be removed and the request codes would probably be a single character in a production environment.

The COBOL I/O Routine
The following is the source listing for the I/O routine (CBLCBLC2.cbl). When an I/O failure occurs the file status code will be displayed. Displaying the file status code takes a little extra effort. Many times the file status code is a two character field and each character is a printable numeric value. However, in some cases the second character may be a COMP value. The error handling in the following program will display the file status code correctly for either format.

Summary
This suite of programs provides an example of how a mainline COBOL program calls a COBOL I/O routine to access a VSAM data set. This document may be used to assist as a tutorial for new programmers or as a quick reference for experienced programmers.
In the world of programming there are many ways to solve a problem. This documentation and software were developed and tested on systems that are configured for a SIMOTIME environment based on the hardware, operating systems, user requirements and security requirements. Therefore, adjustments may be needed to execute the jobs and programs when transferred to a system of a different architecture or configuration.
SIMOTIME Services has experience in moving or sharing data or application processing across a variety of systems. For additional information about SIMOTIME Services or Technologies please contact us using the information in the Contact or Feedback section of this document.

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 simply give us a call or check the web site at http://www.simotime.com
