Relative Record Data Set Delete, Define and Add Records |

Introduction
This program suite provides an example of how to delete and define a new VSAM Relative Record Data Set (RRDS) using Mainframe JCL. Once the new RRDS is created a COBOL program is used to add records to the data set.
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.

JCL Examples
This section will describe the two JCL members used in this example. The first JCL member will delete and define a new Relative Record Data Set or RRDS. The second JCL member will execute a COBOL program that will add records to the data set.
Define a New RRDS
The following (RRC01KJ1.jcl) is a typical example of how to define a new RRDS using the IDCAMS utility program. This JCL member will create a new, empty RRDS.

Add Records to an Existing RRDS
The following (RRA01KJ1.jcl) is an example of how a COBOL program can be used to add records to an existing RRDS. The program will read a file of eighty byte records and write to an RRDS of 128 byte records. The trailing bytes are padded with spaces. The input is included instream in the JCL member.

Summary
The purpose of this example is to show how to create and use a VSAM, Relative Record Data Set (RRDS). This document may be used 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
