Introduction
Convert a file with a record structure that uses a row and column format to an ASCII encoded file with a record structure that uses a Comma Separated Value or CSV format. This test case includes documentation, job scripts and sample programs that describes and demonstrates how to read a column oriented file of fixed length records and fixed length fields and create a comma-delimited file (filename.CSV, Comma-Separated-Value) of variable length fields with the leading and trailing spaces removed from each of the fields. If a field (or data string) contains a delimiter character then enclose the field in double quotes. The program may be adjusted to create a delimited file using a tab, semicolon or other character as the delimiter.
The programs have been tested on an IBM Mainframe System, a Windows system with Micro Focus COBOL and a Linux System with GnuCOBOL.
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.

Programming Input and Output
The following is an example of a file that contains records with predefined, fixed-length fields. This file will be used to create a Comma Delimited file (filename.CSV).The customer number is in positions 1 through 6. Notice that customer numbers 002200, 002300 and 999999 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 following is the record layout for COBOL.

Programming Requirements
This suite of samples programs will run on the following platforms.
| ||||||
| Possible Platforms to Execute this Suite of Sample Programs |
Programming Overview
The main program (CBLCSVC1) will read a Sequential file (TXTGETD1) and produce a 512-byte, variable record length Comma-delimited sequential file (CSVPUTD1). The contents of this file will be variable length fields separated by a comma. The leading and trailing spaces will be removed from each field. Embedded spaces will remain. The source code for the CMD file, the JCL member and the COBOL programs is provided and may be modified to fit your environment.
The following is a flowchart of the job for executing the program to create a Comma Delimited file from a Sequential file of fixed-length fields.

CMD for Batch Job
The following (CBLCSVE1.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 a column-oriented, ASCII/Text file with a fixed-field-length (FFL) and create an ASCII/Text file with a comma-separated-values (CSV) format.

The COBOL Programs
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.
The COBOL I/O Program
The following (CBLCSVC1.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.

Summary
The purpose of this program is to provide examples for accessing a column-oriented, fixed-field-length Sequential file and creating a new comma-delimited, sequential file containing variable-length strings. This document may be used to assist as a tutorial for new programmers or as a quick reference for experienced programmers.
In the world of programming there are many ways to solve a problem. This documentation and software were developed and tested on systems that are configured for a SIMOTIME environment based on the hardware, operating systems, user requirements and security requirements. Therefore, adjustments may be needed to execute the jobs and programs when transferred to a system of a different architecture or configuration.
SIMOTIME Services has experience in moving or sharing data or application processing across a variety of systems. For additional information about SIMOTIME Services or Technologies please contact us using the information in the Contact or Feedback section of this document.

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
