Access JCL Parameters from COBOL

Parameter Passing Access JCL Parameters from COBOL |

Introduction
This suite of programs provides an example of how to pass a parameter string from mainframe JCL to a COBOL program. The COBOL program is written using COBOL/2 dialect but also works 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 job with Micro Focus Server running on Linux, UNIX or Windows. This program may serve as a tutorial for programmers that are new to COBOL and mainframe JCL and as a reference for experienced programmers.
The two techniques use to pass information (a Parameter) from JCL to a program are as follows.

The following sections will explain the parameter-passing in more detail.
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.

Pass a Parameter via PARM=
To pass a parameter from JCL to a program requires the use of the "PARM=" keyword with the EXEC statement. The following JCL statement shows an EXEC statement without a parameter defined.
The JCL Member using PARM=
The following is the JCL member (CBLPARJ1.jcl) required to run as a job on the mainframe. This will also run on a Linux, UNIX or Windows environment using Micro Focus Server. The job contains four steps. The first step will execute the COBOL program (CBLPARC1.cbl) without passing a parameter. The second step will execute the COBOL program and pass a parameter. The third step will execute the COBOL program and pass a maximum size parameter. The fourth step will execute the COBOL program and pass a parameter using a substitution variable for a date value. The JOB statement will need to be modified for specific mainframe environments.

The COBOL Program using PARM=
This program (CBLPARC1.cbl) was written to be used as a teaching and learning aid. When a COBOL program is executed from a JCL member a data string (or parameter) may be passed from the JCL member to the COBOL program using the PARM keyword as follows.
//CBLPARS2 EXEC PGM=CBLPARC1,PARM='datastring'
When the data string is passed from JCL to COBOL it is preceded with a two-byte binary value that specifies the length of the data string. For example, if the data string is ten characters in length the actual information passed to the COBOL program would be a two-byte binary value of ten or x'000A' followed by the ten character data string. If the COBOL program is executed from JCL without a parameter the two-byte binary value would be zero or x'0000'.

Pass Many Parameters via SYSIN
To pass multiple parameters (or records) from SYSIN to a program requires the use of DD statement for SYSIN. The following JCL statement is required if no parameter is passed.
//* ******************************************************************* //* Step 1 of 2, Execute the COBOL program without a parameter. //* //SYSIN DD DUMMY
JCL, SYSIN, Many Parameters
The following is the JCL member (CBLPARJ3.jcl) required to run as a job on the mainframe. This will also run on a Linux, UNIX or Windows environment using Micro Focus Server. The job contains three steps. The first step will execute the COBOL program (CBLPARC3.cbl) without passing a parameter. The second step will execute the COBOL program and pass three parameters as instream data. The third step will execute the COBOL program and pass five parameters using a PDS Member from the PARMLIB. The JOB statement will need to be modified for specific mainframe environments.

Summary
This group of jobs and documentation is intended to help the reader develop a better understanding of how to pass a parameter string from mainframe JCL to a COBOL program. 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
