Table of Contents Previous Section Next Section Introduction

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.


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 ASCII-Text to EBCDIC-Indexed (Sequential Add)

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 Windows command file (IVP4GFC4.cmd) is used to do the generation of the data conversion program.
