Table of Contents Previous Section Next Section Introduction

This suite of sample programs provides an example of a COBOL program doing floating point arithmetic and writing the information to a Sequential file. The program will run on an IBM mainframe or a Windows platform using Micro Focus or a UNIX platform using Micro Focus. On the mainframe the default is to use the IBM 370 Floating Point Arithmetic. On Windows or UNIX using Micro Focus the default is to use the IEEE Standard for Floating Point Arithmetic. The IEEE standard provides a higher level of precision than 370. However, 370 provides for larger numbers by providing less precision.


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.

Logic Flow for Floating Point Example

The main program (CBLFPAC1) will perform calculations using floating point fields. The contents of the fields will be move into a record structure and written to a sequential file. The source code for the CMD file, the JCL member and the COBOL programs is provided and may be modified to fit your environment.

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
