Table of Contents Previous Section Next Section Introduction

This example provides a callable module (SIMOSNAP) that is used to determine the size and dump the content of a COBOL program's WORKING-STORAGE section in a Hex-dump format. The SIMOSNAP routine is intended to be used by application programs currently running on a Linux, UNIX or Windows (LUW) system with Micro Focus. A sample program (CBSNAPC1.CBL) is provided and describes the details of calling and reviewing the output of the snap-dump routine.


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 Programming Objectives

The primary objective is to provide a programmer with a callable routine that will dump the content of a COBOL program's WORKING-STORAGE Section and display the information to a SYSOUT device. A secondary objective is to determine the size of memory area and display this information to the SYSOUT device.

Table of Contents Previous Section Next Section Programming Input and Output

The purpose of the sample programs is to test the DUMP routine. The DUMP routine (SIMOSNAP) is called with two (2) parameters. The parameters are also referred to as "eye-catchers" that identify the start and ending points of the section of memory to be dumped.. The following is an example of a COBOL statement that will call the DUMP routine.

           call 'SIMOSNAP' using STSNAP-START STSNAP-CEASE

The output of the DUMP routine is a display of information to SYSOUT. If JCL is used with the Micro Focus Enterprise Server Mainframe Sub System then the information will be written to the device specified by the SYSOUT DD statement. If a Windows Command file is used the information will be written to the device specified by the SYSOUT environment variable.

The following information (i.e. a Hex Dump of COBOL WORKING-STORAGE) is posted to the SYSOUT device.

This suite of samples programs will run on the following platforms.

1 The DUMP routine was executed and tested on Windows/XP. The samples were executed using Micro Focus Net Express with a Windows CMD file and Micro Focus Enterprise Server with the Mainframe Sub-System option using JCL. Both environments were configured to run in an ASCII encoded environment.
2 The SimoMODS package should be installed prior to using this suite of sample programs. This example uses the SIMOSNAP.CBL program that is provided in the SimoMODS package. Refer to the SimoTime web site for more information.
3 This suite of programs may be ported to run on a LINUX or UNIX platforms supported by Micro Focus COBOL.

Color Associations: The  light-green  boxes are unique to SIMOTIME Technologies using the Mainframe and Micro Focus Enterprise Server/Studio (or Micro Focus Mainframe Express). The  light-red  boxes are unique to the SIMOTIME Technologies using a Linux, UNIX or Windows System and COBOL Technologies such as Micro Focus. The  light-yellow  boxes are SIMOTIME Technologies, Third-party Technologies, decision points or program transitions in the processing logic or program generations. The  light-blue  boxes identify the input/output data structures such as Documents, Spreadsheets, Data Files, VSAM Data Sets or Relational Tables. The  light-gray  boxes identify a system function or information item.

The main program (CBSNAPC1) will call the DUMP routine (SIMOSNAP) which will display the content of WORKING-STORAGE to a SYSOUT device (using a HEX Dump format). The source code for the CMD file, the JCL member and the COBOL programs is provided and may be modified to fit your environment.

Table of Contents Previous Section Next Section The Call Interface

The callable interface requires two data structures to be defined in the Working Storage section of the calling program.

Two copy files are provided to define the "eye-catcher" fields in the COBOL Working Storage Section. The copy statements will create the fields that will be used by the SimoSNAP routine to determine the start and stop addresses for the memory dump.

The first copy statement (STSNAPB1.CPY) should be the first statement in the COBOL Working Storage Section. The second copy statement (STSNAPB2.CPY) should be the last statement in the COBOL Working Storage Section.

       WORKING STORAGE.
      *The following should be the first statement in Working Storage.
       COPY STSNAPB1
      *…
      *The User's Working Storage Definitions go here…
      *…
      *The following should be the last statement in Working Storage.
       COPY STSNAPB2

Note:  The copy files insert sixteen (16) byte literals as the first and last fields in the Working Storage Section. The source code may be viewed in The Copy File section of this document.

The coding to do the actual call to display and/or log the file status information is as follows.

The programs in this packet were created and tested on an intel system with Microsoft Windows/XP and Micro Focus Net Express. The source code and executables are Windows Command files and COBOL programs.

This packet uses members that are part of  The SimoMODS Series of callable programs. Therefore, the SimoMODS packet should be installed prior to running this packet of programs. The required prerequisite programs from the SimoMODS Series are SimoNOTE.CMD, SimoLOGS.GNT and SimoSNAP.GNT.

Table of Contents Previous Section Next Section COBOL Memory Dump Routine

This program (SIMOSNAP.cbl) was originally written to be used as a diagnostic aid for SimoTime consultants and programmers. Today, this program is used by a number of our customers as a diagnostic aid for programming debugging or for tracking the results of program behavior in both a development and production environment. The program has been tested on Windows/XP system with Net Express from Micro Focus.

You may  click here to view the source code for the callable snap dump routine.

Table of Contents Previous Section Next Section Define Working Storage Boundaries

Two copy files are provided to define the "eye-catcher" fields in the COBOL Working Storage Section. The copy statements will create fields that will be used by the SimoSNAP routine to determine the start and stop addresses for the memory dump.

The first copy statement (STSNAPB1.cpy) should be the first statement in the COBOL Working Storage Section. This copy file will create a sixteen (16) byte literal that may be used as an eye-catcher when viewing the memory dump. This literal is used by the SimoSNAP routine to validate the start of the COBOL Working Storage Section.

The second copy statement (STSNAPB2.cpy) should be the last statement in the COBOL Working Storage Section. This copy file will create a sixteen (16) byte literal that may be used as an eye-catcher when viewing the memory dump. This literal is used by the SimoSNAP routine to validate the end (or cessation) of the COBOL Working Storage Section.

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
