Table of Contents Previous Section Next Section Introduction

This suite of sample programs describes how to read a comma-delimited file (filename.CSV, Comma-Separated-Value) of variable length strings and create a column oriented file of fixed length records and fixed length fields. If a string (or data field) contains a delimiter character then process as data. The program may be adjusted to access a delimited file using a tab, semicolon or other character as the delimiter.


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 Programming Objectives

This example illustrates the following functions.

1 Demonstrate how to read a comma-delimited file and create a sequential file (or a Line Sequential file) using Micro Focus COBOL (Net Express was used for the testing).
2 Demonstrate how to parse the comma-delimited string and create fixed-length fields for standard COBOL processing.
3 Demonstrate how to omit blank records from the output file.
4 Provide an example of a Window's CMD file to run the job on Windows using Micro Focus Net Express.
  Programming Objectives, Read and Parse a CSV File for Conversion to Fixed Field Format

The following is an example of a sequential (or Line Sequential) file that contains records with predefined, fixed-length fields. This file was created by a COBOL program that read and parsed strings in a Comma Delimited file (filename.CSV).The customer number is in positions 1 through 12. Notice that customer numbers 000000002200, 000000002300 and 000000999999 contain examples of fields with leading spaces and fields that contain a comma in the data string. All the records have trailing spaces in the fields.

The main program (CBLCSVC2) will read an ASCII/Text file with CSV formatted records (CSVGETD1) and produce a file with the record content being a fixed field format (TXTPUTD1), The record length is 512 bytes.. The source code for the CMD file and the COBOL programs is provided and may be modified to fit your environment.

The following (CBLCSVE2.cmd) is a sample of the Windows CMD needed to run this job. This set of programs illustrates the use of Micro Focus COBOL programs that will read an ASCII/Text file with a comma-separated-values (CSV) format and create an ASCII/Text file with a column-oriented, fixed-field-length (FFL) format.

The conversion process uses two (2) programs. The mainline program does the file I/O and calls the conversion routine to the record content conversion. The following describes the two programs.

Table of Contents Previous Section Next Section The COBOL I/O Program

The following (CBLCSVC2.cbl) is a sample of the Micro Focus COBOL demonstration program. This program will not compile or execute on an IBM Mainframe because of the ORGANIZATION IS LINE SEQUENTIAL on the SELECT statement. If the statement was changed to read ORGANIZATION IS SEQUENTIAL it would run on an IBM Mainframe and "read from" and "write to" a sequential file. The program was tested using Micro Focus Net Express, version 6.0 running on Windows/7.

      * This routine uses reference modification to identify the
      * position of the first significant character after the
      * delimiter character. This approach compensates for multiple
      * leading or embedded delimiter characters. The string function
      * of COBOL does not handle leading spaces.
      *
      * For example, if the delimiter character is a space then
      * leading spaces will be ignored and multiple, embedded spaces
      * will be treated as a single space.

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
