Introduction
One approach to application or data validation is human observation or analysis. Human observation is very useful when evaluating the usability and business flow of an application.
Using this approach for data validation presents the following challenges.
| 1. | Introduces additional risk of human error. |
| 2. | May be useful for small amounts of data. As the volume of data increases the reliability of the "human observation" approach decreases. |
| 3. | Data strings with binary content are not easy to interpret and can be presented in a misleading manner when using a text editor. |
| 4. | The structure of some data strings may require specialized knowledge to properly interpret. |
| 5. | A "hexadecimal dump" presentation of the data may be required. |
Because of these challenges the "human observation" approach is considered as a "reasonability check" or "diagnostic aid". Typically, a programmatic methodology that can be automated and run without human intervention will be a requirement.
This document will focus on a process that will generate a single COBOL program that will create a Hexadecimal dump file (or HEXDUMP) of user-defined records contained in an indexed data structure or file. On an IBM Mainframe System this would be a VSAM, Key Sequenced Data Set (KSDS). The Hex-Dump formatting and file I-O are done within the single COBOL program.
The program (HX80KSC3) will be generated using SimoTime Technologies and will compile and execute on a Linux, UNIX or Windows System with Micro Focus Enterprise Developer/Server, version 2.2 or later.
The HX80KSC3 program should compile and execute on a ZOS Mainframe. The JOB statement and the data set names (DSN's) will need to be changed to comply with security and naming standards on the host mainframe system.
Note: The unit testing was done on a Windows System with Micro Focus Enterprise Developer configured for an ASCII-encoded environment.
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.

Diagram of Hex-Dump Process
The following diagram shows the batch processing and data flow for a job that will do a HEX-Dump of user-defined records in a VSAM, KSDS.

The VSAM, KSDS for this example is an indexed data structure containing customer data.
Sample Hex-Dump Output
The following shows the HEX-Dump of user-defined records in a VSAM, KSDS.
The following is a Hex-Dump of two records in the Customer File. The records were selected by using a control file that contained a list of primary keys.
The 1st line is the position indicator.
The 2nd line is the possible EBCDIC character or symbol.
The 3rd line is the high-order nibble of the byte for the Hex-dump.
The 4th line is the low-order nibble of the byte for the Hex-dump.
The 5th line is the possible ASCII character or symbol.

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
