Data File Conversion A SimoPATH Task  View COBOL Source Code

Introduction
(Next) (Previous) (Table-of-Contents)

This document describes how to view and validate the generation of the COBOL source code for two programs. The first program will read an EBCDIC encoded file and write an ASCII encoded file. The data conversion will be performed by a second COBOL program that is called by the first COBOL program. Since the COBOL source code is COBOL/2 compliant it may be compiled and executed on an IBM Mainframe (z/OS or VSE), a Wintel platform (Windows and Micro Focus) or a UNIX platform (with Micro Focus).

This example illustrates the following functions.

Note: This module is part of The SimoPATH Series of training and reference materials. For more information refer to The Home Page for The SimoPATH Series.

Generating the COBOL source code to do the data file conversion is a two step process. The first step is to create the callable conversion program using the copy file as input. The second step is to create the I/O program using the specifications file as input.

The following source member should be displayed using Notepad.

The SimoZAPS Utility Program has the capability of generating a COBOL program that will do the conversion of sequential and VSAM (KSDS) files between EBCDIC and ASCII. SimoZAPS can also read a sequential file in EBCDIC format and create an ASCII/CRLF file or VSAM KSDS file in ASCII format. The conversion tables may be viewed or modified to meet unique requirements. The Hexcess/2 function provides the capability of viewing, finding or patching the contents of a file in hexadecimal.

The SimoREC1 Utility Program has the capability of generating a callable COBOL program that will do the conversion of a data string between EBCDIC and ASCII. The generated COBOL source code or the conversion tables may be viewed or modified to meet unique requirements. The generated program may be called by an I/O program generated by SimoZAPS.

This item will provide a link to  an ASCII or EBCDIC translation table. A column for decimal, hexadecimal and binary is also included.

This document provides a quick summary of the  File Status Key  for VSAM data sets and QSAM files.

Check out  The VSAM - QSAM Connection  for more examples of mainframe VSAM and QSAM accessing techniques and sample code.

The hexadecimal dump of the parameter-buffer uses the same technique as describe in another SimoTime example that describes the dumping of a data string using COBOL. The name of the member that does the actual hexadecimal dump is called SimoDUMP. A copy file (PASSDUMP.CPY) is provided for defining the pass area.

You may view the complete list of examples at http://www.simotime.com/sim4dzip.htm and many are available as a SimoTime Z-Pack (a zip file package with sample source code, data and documentation).

Note: You must be attached to the Internet to download a Z-Pack or view the list.
