This is an example of how a COBOL program can read an ASCII/Text file and write an EBCDIC-Indexed file. The COBOL source code was generated using SimoZAPS, a product of SimoTime Enterprises. The SimoZAPS utility program also has the capability of reading, writing or converting between other file formats.
In the world of programming there are many ways to solve a problem. This program is provided as a COBOL example of one of the possible solutions to the problem of changing the contents and structure of data files.
This program will read an ASCII-Text file and write to an EBCDIC-Indexed (VSAM, KSDS - Keyed Sequential Data Set) file. The keys must be in sequence for the writes to the output file.
The sorting or collating sequence for ASCII and EBCDIC are different and produce different results. For example, with ASCII the numbers are sorted before the alphabet and with EBCDIC the numbers are sorted after the alphabet. If the key field is a combination of numeric and alphabetic characters it will probably be necessary to sort the ASCII-Text file prior to writing to the EBCDIC-Indexed file. Another alternative is to do an unordered load (or random-add) of the Indexed or KSDS file. This approach is slower than an ordered load but does allow for the key-fields to be added randomly to the indexed or KSDS file.
The following is the source code for the file conversion. This program was compiled and tested on the PC using Mainframe Express (with the non-mainframe dialect) and Net Express (refer to http://www.microfocus.com ). Since the organization of the input file (SYSUT1) is specified as LINE SEQUENTIAL (the Micro Focus terminology for ASCII Text files) this program will not compile or execute on the mainframe.

The purpose of this document is to assist as a tutorial for new programmers or as a quick reference for experienced programmers. These sample programs are made available on an "as-is" basis and may be downloaded, copied and modified for specific situations as long as the copyright information is not removed or changed. As always, it is the programmer's responsibility to thoroughly test all programs.
Take a look at the Table of ASCII and EBCDIC values.
The SimoZAPS Utility Program runs on a Windows platform and 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 Keyed Sequential Data Set in ASCII format. The conversion tables may be viewed or modified to meet unique requirements. The Hexcess/2 function of SimoZAPS provides the capability of viewing, finding or patching the contents of a file in hexadecimal. The following is a list of a few conversion programs created by the GENERATE function of SimoZAPS.
| Program Name | Description |
| zap00101 | Convert from an EBCDIC-Sequential file to an ASCII-Text file. |
| zap00201 | Convert from an EBCDIC-Sequential file to an ASCII-Indexed file (Sequential-Add). |
| zap00301 | Convert from an EBCDIC-Sequential file to an ASCII-Sequential file. |
| zap00401 | Convert from an ASCII-Text file to an EBCDIC-Indexed file (Sequential-Add). |
| zap00501 | Convert from an ASCII-Text file to an EBCDIC-Indexed file (Random-Add). |
Check out The COBOL Connection for more examples of mainframe COBOL coding techniques and sample code.
Check out The VSAM-QSAM Connection in the SimoTime Library for more examples of mainframe COBOL techniques and sample code.
This document provides a quick summary of the File Status Key for VSAM data sets and QSAM files. The File Status Key is a two character data item. The first character of the status key is known as status key 1; the second character is known as status key 2.

Founded in 1987, SimoTime Enterprises 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. This includes the smallest thin client using the Internet and the very large mainframe systems. There is more to making the Internet work for your company's business than just having a nice looking WEB site. It is about combining the latest technologies and existing technologies with practical business experience. It's about the business of doing business and looking good in the process. 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.
