VSAM with Text & Binary Data Strings

HEX Dump of a KSDS VSAM with Text & Binary Data Strings |
|
| The SimoTime Home Page |
Introduction
This is an example of how a COBOL program can read from an Indexed file (or a VSAM KSDS) and write to a sequential file (ASCII/Text or Record Sequential) that will contain HEX dump information of a data structure with Text, Packed and Binary Data Strings (or User Defined Fields). The COBOL source code is generated using SimoTime Technologies.
The technique of using a generated COBOL program delivers a solution that may be compiled and executed on an IBM Mainframe System (running ZOS or VSE) and/or a Linux, UNIX or Windows System running Micro Focus Enterprise Server.
In the world of programming there are many ways to solve a problem. This program is provided as a COBOL example of one of the possible solutions to providing a diagnostic tool for viewing records in a VSAM, KSDS in a HEX-Dump format.
Note: Providing the capability of viewing information in data files will need to be reviewed from a privacy and security perspective based on the requirements of the business.
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 - Produce Hex-Dump Output
This section describes the two jobs (JCL Members) that are included in this example. The first JCL Member (KSAHEXJ2.jcl) will dump the content of every record in a file. This may be an acceptable solution in a development or test environment where the test files are small.
For larger files the second job (KSAHEXJ3.jcl) offers an alternative solution to select the records to be dumped by defining the keys of the records in a control file (SYSUT3).
JCL - HEX Dump for a File
This HEX-Dump job is targeted for a "Mainframe-oriented" environment using ZOS or Micro Focus Enterprise Developer/Server.
The input is a VSAM Key-Sequenced-Data-Set (KSDS) or a Micro Focus Indexed (or key-sequenced) file with 512 byte records that may contain text-strings, packed and/or binary data. The key is 12 bytes in length and starts in position 1 of each record.
The output will include all the records in the file. It produces the HEX-Dump output to a record sequential file with a fixed record length that is equal to the record length of the input file.
The following JCL Member (KSAHEXJ2.jcl) is a multi-step job that will initialize the environment and produce a HEX Dump file of a VSAM KSDS (or Indexed Data Structure).

JCL - HEX Dump for Selected Records
This HEX-Dump job is targeted for a "Mainframe-oriented" environment using ZOS or Micro Focus Enterprise Developer/Server.
The input is a VSAM Key-Sequenced-Data-Set (KSDS) or a Micro Focus Indexed (or key-sequenced) file with 512 byte records that may contain text-strings, packed and/or binary data. The key is 12 bytes in length and starts in position 1 of each record.
The output will include selected records based on the keys defined in SYSUT3 (a record sequential control file). It produces the HEX-Dump output to a record sequential file with a fixed record length that is equal to the record length of the input file.

Sample Hex-Dump Output
The HEX-dump may provide up to six lines of information based on the user-defined parameters.
The following is an example of the HEX-Dump output for a VSAM, KSDS. After the header information the dump format for each record is as follows.
The first two lines are the position indicators that show the byte position within the record.
The third line show the possible ASCII character translation
The fourth and fifth lines contain the HEX Dump information. The fourth line is the high-order nibble (four bits) of the byte. The fifth line is the low-order nibble (four bits) of the byte.
The sixth line is the possible EBCDIC character translation.

Prepare
Creating a process and an environment for the development and deployment of a utility program or suite of programs requires planning, preparation and execution. This section will focus on the preparation effort to create a utility program that will provide a Hex-Dump capability for a VSAM, Key-Sequenced-Data-Set (KSDS). For non-relational data structures this process will leverage a variety of skills and a broad knowledge base that may be acquired through training, experience, research and assistance.
Create a Process Control File
In this example we will generate a COBOL program that will read a VSAM, KSDS and write to a HEX Dump file. The following member (KSAHEX01.pcf) is the Process Control File used to generate the COBOL program.

* This program mask is used with a callable subroutine that *

* *
* If the output file is indexed then the input file must be in *

Summary
This is an example of how a COBOL program can read from an Indexed file (or a VSAM KSDS) and write to a sequential file (ASCII/Text or Record Sequential) that will contain HEX dump information of a data structure with Text, Packed and Binary Data Strings (or User Defined Fields).

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
