Entry Sequenced Data Set Delete, Define and Adding Records |
|
| The SimoTime Home Page |
Introduction
This program suite provides an example of how to delete and define a new Entry Sequenced Data Set (ESDS) using Mainframe JCL. Once the new ESDS is created a COBOL program may be used to add records to the data set. You can update records in place, but you cannot delete them. You can get around this by having a "status" field within the record that identifies it as being logically deleted. At some point in time you should copy the file and drop all the logically deleted records. This approach requires all applications that access the data set to know the meaning of the "status" field.
Note: The record length of the replacement record must be the same as the record length of the record being updated.
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 Members
This section will describe the two JCL members used in this example. The first JCL member will delete and define a new Entry Sequenced Data Set or ESDS. The second JCL member will execute a COBOL program that will add records to the data set.
Define a New ESDS
The following (ES128CJ1.jcl) is a typical example of how to define a new ESDS using the IDCAMS utility program. This JCL member will create a new, empty ESDS.

Add Records to an Existing ESDS
The following (ES128UJ1.jcl) is an example of how a COBOL program can be used to add records to an existing ESDS. The program will read a file of eighty byte records and write to an ESDS of 128 byte records. The trailing bytes are padded with spaces. The input is included in stream in the JCL member.

*****************************************************************
* This program was created with the SYSMASK1.TXT file as input. *
* The SYSMASK1 provides for the sequential reading of the input *
* file and the sequential writing of the output file. *
* *
* If the output file is indexed then the input file must be in *
* sequence by the field that will be used to provide the key *
* for the output file. This is a sequential load process. *
* *
* If the key field is not in sequence then refer to SYSMASK2 *
* to provide for a random add or update of the indexed file. *
* *
* This program mask will have the ASCII/EBCDIC table inserted *
* for use by the /TRANSLATE function of SimoZAPS. *

Write Records using CICS COBOL
The following (WTL128.cbl) is a link to a sample CICS, COBOL program that will add records to a VSAM, Entry Sequenced Data Set or ESDS.

Technical Details
This section describes additional technical details not covered in previous sections of this document.
Compiler Options or Directives
This document provides information about how to specify and use the Micro Focus COBOL compiler directives that may be required to control program behavior in the Linux, UNIX or Windows environments in a manner compliant with the compiler options and subsequent execution on the Mainframe System.
Explore the Compiler Directives available for the Micro Focus COBOL technologies.
Alternate Compiler Directives for ESD128C0
The following compiler directives were used to compile the ESD128C0 program.
DIALECT"OS390" CHARSET"ASCII" ASSIGN"EXTERNAL" IBMCOMP NOTRUNC HOSTNUMMOVE HOSTNUMCOMPARE NOSIGNFIXUP HOSTARITHMETIC CHECKNUM filetype"15" ANIM NOOPTIONAL-FILE outdd"SYSOUT 121 L" SHARE-OUTDD DATAMAP settings list() noform
Note: The FILETYPE"15" will enable a COBOL program to process a VSAM, ESDS (Entry-Sequenced-Data-Set). A FILETYPE"16" compiler directive would enable a COBOL program to process extended VSAM, ESDS's (Entry-Sequenced-Data-Sets).
Summary
The purpose of this example is to show how to create and use a VSAM, Entry Sequenced Data Set (ESDS). 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.

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
