Table of Contents Previous Section Next Section Introduction

This document provides a listing of the COBOL source code for a callable routine that provides read access to a Line Sequential (or ASCII/Text) file. This program is included in the SimoCARD suite of programs.


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 How to Use

The SimoGL80 program provides an easy to use, callable routine for accessing or reading records from a line sequential file with a maximum record length of 80-bytes.

First, the pass area (or data structure) must be defined in the WORKING-STORAGE section of the program that will call SIMOGL80. A COBOL copy file is provided for this purpose and the same copy file is used in the LINKAGE section of SIMOGL80.

       COPY PASSGL80.

Next, the data items in the pass area need to be initialized prior to calling SIMOGL80.

           move 'OPEN    ' to GL80-FILE-REQUEST
           move ZERO       to GL80-FILE-STATUS 
           move SPACES     to GL80-PASS-80     

Next, the following shows the line of code that makes the call to SIMOGL80.

           call 'SIMOGL80' using GL80-PASS-AREA

The following is a list of the parameters required when using the GL80-PASS-AREA to call the SimoGL80 routine.

Parameter  Description
GL80-PASS-REQUEST  This parameter must be provided by the calling program.
Keyword Description
READ  Get a logical record from an ASCII/Text (or Line Sequential) file.
OPEN  Open for INPUT will open the file for read access only..
CLOSE  Close the file.
GL80-PASS-STATUS  A zero (0) value indicates a successful completion of the request. A non-zero value indicates the request could not be completed successfully.
GL80-PASS-80  This parameter will contain the logical record for a READ request.

Note:  A listing of the COBOL copy file is provided in a following section of this document.

Table of Contents Previous Section Next Section Mapping the Data File Name

The SimoGL80 program that reads a record sequential file uses the file name of "GET080LS" when accessing the file. To have the program access the correct file the location and name of the physical file must be mapped to the name used by the program. This is accomplished by using an environment variable. The following shows how this is accomplished.

set GET080LS=d:\mydirectory\filename.ext

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
