Introduction
This suite of programs will create two data arrays (or table definitions) that may be used to display binary characters in a hexadecimal format. The two data tables will be saved as COBOL Copy Files. This example includes two COBOL programs with the JCL Members and Window Command Files for execution. The first COBOL program will create a table or 256 elements or a text string of 256 bytes that will contain the binary values from X'00' through X'FF'. The program will also create a 512 byte text string of two-byte pairs that may be used to display a field or text string in a hexadecimal dump format. Once the text strings of binary and display values are created they are written to files that may be used as a COBOL copy files by other programs.
The second COBOL program will use the copy files created by the first program to insert binary data into a text string and display the text string in a hexadecimal dump format.
The source code for the CMD file, the JCL member and the COBOL programs is provided and may be modified to fit your environment. The COBOL programs will run on an IBM, ZOS Mainframe System or in a Micro Focus environment on Windows.
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.

Sample Routines
The intent of this section is to provide a summary of the sub-routines by function and a quick link to the sub-routines within the main program.
Create a Binary Table
This sub-routine shows how to create a text string of 256 bytes that will contain the binary values from X'00' through X'FF'.
Click on this link to view the code in the program that does the Create a Binary Table. This will be displayed in a separate window.
Compare the Tables of Binary Values
This sub-routine will compare the contents of the table just created with a binary table that is predefined by a COBOL Copy file.
Click on this link to view the code in the program that does the Compare the Tables. This will be displayed in a separate window.
Create 256-Byte String of Binary Values
In the mid-1980's IBM provided an extension to the ANSI/85 COBOL with their version of COBOL/2. This extension allowed a programmer to define any of the hexadecimal from X'00' through X'FF'. This capability was later included in the ANSI/2002 standard.
Click on this link to view the code in the program that does the Create a Copy File of Binary Values. This will be displayed in a separate window.
Create 512-Byte String of 2-Byte Text
This section describes how to create a 512 byte text string consisting of two (2) byte pairs of data. Each two (2) byte pair represents a text string that shows the value of a hexadecimal byte. Each two (2) byte pair may be displayed or printed.
Click on this link to view the code in the program that does the Create a Copy File of Display Text. This will be displayed in a separate window.
Job Scripts
A job script may be defined as a text file containing job setup information followed by job steps that identify programs to be executed along with parameters unique to the job step. A job script may be created using a text editor. The naming of a job script is determined by the Operating System. A simple job script may contain a single job step that performs a single function. A typical job script will contain multiple job steps executed in a predefined sequence. The status of each job step may be tested at the end of each job step.

The following (BINBITJ1.jcl) is a sample of the Mainframe JCL needed to run this job.

Summary
This suite of programs will create two data arrays (or table definitions) that may be used to display binary characters in a hexadecimal format. The two data tables will be saved as COBOL Copy Files. 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.
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
