Table of Contents Previous Section Next Section Introduction

This suite of programs provides an example of how a mainline COBOL program calls a mainframe assembler (HLASM) I/O routine to access a QSAM file. The file is a flat, sequential file. The COBOL program is written using COBOL/2 dialect but also works with COBOL for MVS and COBOL/370. The assembler IO routine 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 PC with Windows.

Another example of accessing QSAM files that uses a called COBOL I/O program is also provided. One of the differences between the COBOL I/O member and the Assembler I/O member is the COBOL module requires the record length to be pre-defined. This would require a separate COBOL I/O member for each file with a different record length. The Assembler I/O member will do an OPEN of a file and the record-length is returned in the DCB (Data Control Block). Since assembler has access to the DCB this information is extracted and returned to the calling COBOL program in the Pass-Area. This capability allows one Assembler I/O member to access sequential files of various record lengths. In this example the calling COBOL program only has a data buffer of 4,096 bytes. Therefore, this is an arbitrary limit for the record size the called Assembler I/O member is allowed to access. This arbitrary limit may be increased.

This program may serve as a tutorial for programmers that are new to COBOL, 370 Assembler or QSAM and as a reference for experienced programmers. Additional information is provided in the Downloads and Links to Similar Pages section of this document.

The following summarizes the items needed for the calling COBOL program (QSAMIOC1) to call the Assembler program (QSAMIOA1).

The "calling COBOL program" contains the following statement to make the call to the "called Assembler program".

CALL 'QSAMIOA1' USING PASS-AREA

The source code listings for both the Caller COBOL program and the Called Assembler I/O routine are included within this document.

The following COBOL copy file(QSAMIOB1.cpy) is used in the WORKING-STORAGE section of the Caller program to define the data structure for the pass area that will be used by the Caller and Called programs.

The following is the mainframe JCL (QSAMIOJ1.jcl) required to run as an MVS job on the mainframe. This job will also run with Micro Focus Mainframe Express. The coding technique is used with the expectation the JCL would be used as a stand alone procedure.

This program (QSAMIOC1.cbl) was written to be used as a teaching and learning aid. The displays are not required and the parameters use full words. The displays would probably be removed and the request codes would probably be a single character in a production environment.

Table of Contents Previous Section Next Section The Assembler I/O Routine

This program (QSAMIOA1.mlc) does not provide much visual information when it is executed on the mainframe. The real value to this program is when it is animated using the 370 Assembler Option of Mainframe Express provided by Micro Focus. It is possible to watch the actual execution of each individual instruction and to immediately see the results.

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 or need assistance with converting non-relational data structures simply give us a call at 415 883-6565 or check the web site at http://www.simotime.com
