Data Structure, TCNTXTB1 Generated from a COBOL Copy File

Introduction

This document was generated from a COBOL copy file using the SIMOTIME Record Layout utility program. The primary intent of the following table is to provide additional information about a file record layout using a COBOL Copy File as input. For example, the position of a field within a record is not easily determined from the COBOL Copy FIle. Also, the actual physical length for group items, packed fields, binary fields and tables is not explicitly defined. This information is calculated and provided by the SIMOTIME Record Layout utility program.

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.

Record Structure

The physical length for the BINARY or COMP fields is calculated based on the format for an IBM Mainframe

COBOL Copy File

The following shows the content of the COBOL Copy File that defines the fields within a record structure (or record layout).

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
