Table of Contents Previous Section Next Section Introduction

The STPEEKC1 routine (or callable program) will access a user defined binary string of data and create a text string of data in a hex-decimal notation format that may be displayed or used in a review process that requires human observation.

This document provides a listing of the COBOL source code for the callable routine STPEEKC1. Additional information about this program may be obtained by sending an e-mail to: helpdesk@simotime.com


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.

Table of Contents Previous Section Next Section STPEEKC1, What It Does

The STPEEKC1 routine (or callable program) will convert a user defined segment of memory to a text string of data in a hexadecimal notation format. The hexadecimal notation may be displayed or written to an ASCII/Text logging file.

The following is an example of the hexadecimal dump information provided for an ASCII encoded data string that contains "ABCDEFGHIJKLMNOPQRSTUVWXYZ".

Each single byte in the preceding string will produce two bytes of hexadecimal notation. The Hex Notation may be presented in 1 of 2 formats.

Format 1 will present a single line of Hex Notation.

Hex Notation: 4142434445464748494A4B4C4D4E4F505152535455565758595A

Format 2 will present two lines of Hex Notation. The first line shows the content of bits 0-3 for each byte of data. The second line shows the content of bits 4-7 for each byte of data.

1st Nibble is 44444444444444455555555555
2nd Nibble is 123456789ABCDEF0123456789A

Note: Bits 0-3 may be referred to as the 1st nibble of a byte of data. Bits 4-7 may be referred to as the 2nd nibble of a byte of data.

Table of Contents Previous Section Next Section STPEEKC1, How To Use

The coding to do the actual call to display and/or log the hexadecimal dump information is as follows.

      *****************************************************************
      *    The coding required to do the call to the Hex-Dump program.
      *    ------------------------------------------------------------
           CALL 'STPEEKC1' USING STPEEK-USR-DATA,
                                 STPEEK-USR-SIZE,
                                 STPEEK-HEX-DUMP,
                                 STPEEK-HEX-TYPE

A copy file is provided to define the pass area to be used when calling STPEEKC1. The following statement is required in the WORKING STORAGE section of the calling program.

Table of Contents Previous Section Next Section 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
