EXEC CICS SPOOL Submit JCL to INTRDR from CICS |

Introduction
This example uses a COBOL program running under CICS to submit a batch job (i.e. JCL) to the Internal Reader (or INTRDR). The program uses command level CICS statements (EXEC CICS SPOOL) to access the internal reader. The program will run on an IBM Mainframe System with CICS or a Microsoft Windows System with Micro Focus Server and the Mainframe Sub-System option.
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 CICS Transaction (JRDR)
Start a 3270 Session and execute the "JRDR" Transaction. The following is an overview of the Batch Job submission process.

| Overview of the Process for submitting a Job to the JES Internal Reader using EXEC CICS SPOOL |
The Batch Jobs
This example includes two batch jobs. The first job (CCSRDRJ8.jcl) is provided as a reference point. It is a standard JCL member that is submitted and executed in the traditional batch environment. The second batch job is submitted to the internal reader (INTRDR) from within a COBOL program running in a CICS environment. A JCL member does not exist. The JCL statements are created from data defined in the WORKING-STORAGE section of the COBOL program and written to the INTRDR. When all the JCL statements have been written to the INTRDR the job is executed.
JCL Member for Reference Sample
This JCL Member (CCSRDRJ8.jcl) is provided as a sample job that is submitted and executed in the JES Batch environment.

CICS Program to INTRDR
The following JCL Member (CCSRDRJ9.jcl) does not exist as a JCL Member. Each JCL statement is a data item in the WORKING-STORAGE section of the COBOL program (CCSJCLC1.cbl. The following is a list of the JCL statements created and submitted by the COBOL program running in the CICS environment.

The COBOL Program
The COBOL program (CCSJCLC1.cbl) uses the EXEC CICS SPOOL capabilities to submit a batch job to the internal reader (INTRDR) from within a CICS Program. The following is an example of the source code.

Summary
This example uses a COBOL program running under CICS to submit a batch job (i.e. JCL) to the Internal Reader (or INTRDR). 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.
