This 370 Assembler program provides different techniques for using the SS Format of the Translate (TR) Instruction. The assembler program is written to comply with an IBM Mainframe Assembler dialect. The program will compile using Assembler/H or HLASM. A JCL member is provided as a job script to run as a batch job on an IBM Mainframe System with ZOS or a Windows System with Micro Focus Enterprise Developer.

The bytes at the storage address specified by operand-1 (b1+d1) are replaced by the byte located at the calculated address within operand-2 (b2+d2).

The address is calculated from x2+d2 and the byte value from operand-1

This program may serve as a tutorial for programmers that are new to 370 Assembler and as a reference for experienced programmers.


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.

The following is the mainframe JCL (AITR00J1.jcl) required to run the assembler program. The JOB statement will need to be modified for specific mainframe environments. This will also run on a Windows System using Mainframe Express provided by Micro Focus.

This program (AITR00A1.mlc) abides by the mainframe calling protocol and register usage guidelines. Register-15 is used to pass a return-code and register-14 contains the return address for the calling program. This program executes a routine that use the TR Instruction to convert a string of lower case characters to upper case. A HEX-Dump routine is used to display the memory used by the program.

Table of Contents Previous Section Next Section 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
