Table of Contents Previous Section Next Section Introduction

This suite of programs will describe how to submit a second job to the internal reader from within the currently running job. A small sequential file is created by the second JCL member.

The source code, data sets and documentation are provided in a single zipped file called INTRDR01.ZIP. This zipped file may be downloaded from the SimoTime Web site. In the Windows environment the file names have file extensions. If the JCL member is uploaded to a ZOS Mainframe from the Windows and Micro Focus environment the file extension is 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 Sample JCL

This example contains two (2) JCL members. The first JCL member uses IEBGENER to copy a second job into the internal reader. The "COPY" or "REPRODUCE" function is standard for IEBGENER. What makes this use of IEBGENER unique is the definition of the INTRDR by SYSUT2.

When the second JCL member is executed it uses IEBGENER to create a sequential file.

Note: Depending on the system environment and if the primary and secondary jobs are the same class then the secondary job may not execute until the primary job completes.

Table of Contents Previous Section Next Section Submit a 2nd Job via Internal Reader

The following mainframe JCL (INTRDRJ1.jcl) uses IEBGENER to submit a second job via the Internal Reader (INTRDR). The IEBGENER utility is commonly used to copy one sequential data set to another. The file to be copied is SYSUT1 and the output file is SYSUT2. A JCL member of a partitioned data set (PDS) can be defined by SYSUT1. When SYSUT1 is a PDS Member that contains JCL statements and SYSUT2 is SYSOUT=(,INTRDR) the JCL member is copied to the internal reader (or submitted to the internal reader). The key to this technique is the definition used by SYSUT2. IEBGENER thinks it is doing a simple 80/80 Repro or making a copy of a file.

Table of Contents Previous Section Next Section 2nd Job to be Processed via INTRDR

The following mainframe JCL (INTRDRJ2.jcl) is used to copy records (from an instream string of records defined by SYSUT1) to an output file that is defined by SYSUT2. This is a common use of IEBGENER. In this suite of sample programs this JCL member is submitted to the Internal Reader from the Primary JCL member described in the preceding section of this document.

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
