Table of Contents Previous Section Next Section Introduction

This document will focus on the use of macro and copy files in a High Level Assembler (HLASM) program. For the Micro Focus environment the physical location of the macro and copy files is defined in a configuration file.

This is a very simple example of a mainframe assembler program that uses one copy file and two macro files. The copy file is stored in a user copy library. The macro files are stored in a user macro library. However, the second macro file is categorized as a copy file.

The assembler program is written in IBM Mainframe Assembler, it will compile using Assembler/H or HLASM. A JCL member is provided to run the job as an MVS batch job on an IBM mainframe or as a project with Micro Focus Mainframe Express (MFE) running on a Windows System.

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.

Table of Contents Previous Section Next Section The Mainline Assembler Program

The primary objective of this program is not in the execution process but in the compile process. Since the reference to the second macro (ASMMACB2.cpy) is stored as a copy file the Micro Focus Assembler must be configured to handle multiple extensions for macro files.

During execution this program (MACCPYA1.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 simply does a subtract of Register-15 from itself (i.e. setting the value to zero) and then does an unconditional branch to the address specified in Register-14.

Note:  The unusual thing about this used-defined Macro File is that it is categorized as a copy file and has a .cpy extension appended to the file name.

Table of Contents Previous Section Next Section Compile the program

Since this example contains a macro file that is categorized as a copy file the Micro Focus environment variable must be set in order for the compiler to look for multiple extensions for macro files (the default is to look for files with a .mac extension). The following statement is an example that may be used to set the environment variable.

SET MACROEXT=CPY,MAC

The environment variable may be set in the MF370CTL.CFG file that is provided by Micro Focus.

The following(ASMMFCTL.cfg) is an example of a MF370CTL.cfg file that is provided by Micro Focus. This example contains some typical "user" modifications. It has been renamed to avoid accidently overlaying the original MF370CTL.cfg file.

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
