Files with Different Record Lengths
|
File Merge or Concatenate Files with Different Record Lengths |
|
| The SimoTime Home Page |
Introduction
This suite of programs will describe and demonstrate how to merge or append (concatenate) multiple files of various record lengths into a single file. For example, the first file is a sequential file with fixed-length records of 80 bytes. The second file is a sequential file with fixed-length records of 60 bytes. The third file is a sequential file with fixed-length records of 40 bytes.
This package includes a job (JCL Member) that will create the test files. The techniques for merging or appending the files will use IEBGENER, IDCAMS, ICETOOL, ICEMAN, DFSORT or SORT.
Note: The jobs in this suite of programs would be much simpler if all the input files had the same characteristics (i.e. the same file type with the same record length).
Within the scope of this document we will use the term "merge" when the task will actually merge the files and intersperse the individual records of the files based on the content of a user-defined field within each record. This approach requires the input files to be sorted into sequence based on the content of the user-defined field.
Within the scope of this document we will use the term "append" when the task simply copies the first file to a new file and then appends the second and third file to the end of the new file. The sequence of the records will be the same as the sequence within the original files. The technique may be referred to as file concatenation.
The process of merging or appending files is fairly simple when all the input files have the same characteristics or properties such as file type and record length. It does require extra consideration if the file properties or record lengths are different. This document uses files with different record lengths.
| 1. | MRGCPYJ1 - this job will use IEBGENER to append the three files together into one file. |
| 2. | MRGCPYJ2 - this job will use the REPRO function of IDCAMS to concatenate the three files into one file. |
| 3. | MRGCPYJ3 - this job will use SORT with concatenated SORTIN files to copy the three files into one file. |
| 4. | MRGCPYJ4 - this job will use ICETOOL/ICEMAN with multiple SORTIN01, SORTIN02 and SORTIN03 to merge the three files into one file. |
| 5. | MRGCPYJ8 - this job will use IEBGENER to create the three files to be used as input for the merge jobs. |
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.

Preparation
The jobs included in this suite of programs will execute on an IBM Mainframe System with ZOS or a Linux, UNIX or Windows System with Micro Focus Enterprise Developer. Therefore, it will be necessary to have a properly configured system that is capable of executing JCL that use the standard data file utility programs. programs. The techniques for merging the files will use IEBGENER, IDCAMS, SORT, ICETOOL, ICEMAN and IEFBR14.
Next, a set of three test files will be necessary. The following sub-section describes a job for creating the test files.
Create Three Test Files
This job uses a single JCL member (MRGCPYJ8.jcl) to create the three (3) test files with different record lengths to be used as input for the jobs that do the file merging.

Summary
This suite of programs will describe and demonstrate how to merge or append (concatenate) multiple files of various record lengths into a single file. 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.

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
