Table of Contents Previous Section Next Section Introduction

This suite of programs provides an example of how a single mainline COBOL program accesses a QSAM or Sequential file. The COBOL program is written using COBOL/2 dialect but also works with COBOL for MVS and COBOL/370. A JCL member is provided to run the job as an MVS batch job on an IBM mainframe or as a project with Micro Focus Mainframe Express (MFE) running on a PC with Windows.

This example may serve as a tutorial for programmers that are new to COBOL or QSAM-Sequential file processing. This example may also be used as a reference for experienced programmers.


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.

The following is the mainframe JCL (CBLQSMJ3.jcl) required to run as an MVS batch job on the mainframe. This will also run on the PC with Micro Focus Mainframe Express. The coding technique is used with the expectation the JCL would be used as a stand alone procedure.

This program (CBLQSMC3.cbl) was written to be used as a teaching and learning aid. It is a simple program that reads a sequential file and displays the records. Notice the "Z-DISPLAY-IO-STATUS" routine to display the file status code.

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 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
