Sequential File Format and Record Content Conversion

Record to Line, EBCDIC to ASCII Sequential File Format and Record Content Conversion |

This suite of sample programs describes how to read a record-sequential, EBCDIC-encoded file, convert the record content and write to a line sequential, ASCII-encoded file. The first COBOL program does the file format conversion from record sequential to line sequential and calls the second COBOL program to do the record content conversion between EBCDIC and ASCII. Both of the programs were compiled using a Micro Focus dialect since the I/O module writes to a line sequential (or ASCII/Text) file. The programs were generated using SimoTime technology.
The following (E2A256E1.CMD) is a listing of the Windows CMD needed to run this job.

The following (E2A256C1.CBL) is the COBOL I/O program that was generated with SimoTime technology. The program was tested using Micro Focus Enterprise Server on Windows/XP. The program was successfully executed in both an EBCDIC and ASCII encoded configuration. This program will do the File-Format (i.e. Record-Sequential to Line Sequential) conversion.
