The DISPLAY function of COBOL will display a message upon a user's console or the system operator's console in an MVS environment. The content of the message is determined by a user-defined seqment of data stored in random access memory (RAM). This function is quite often used to display information in routines that are performing an abnormal termination of a program. Also, this function may be used as a debugging or diagnostic tool. This approach provides valuable information when a failure occurs. However, there are times when a field or data string may have information that contains non-printable or non-displayable characters. A callable routine that would display a field or data string in a hexadecimal dump (Hex-Dump) format along with a possible EBCDIC and ASCII interpretation could be an effective tool in providing this information.

This suite of programs provides a demonstration program and a callable program to display a data string in a Hex-Dump format for both EBCDIC and ASCII. Both COBOL programs were written and tested using the COBOL/2 dialect. Also, both COBOL programs will work with COBOL for MVS and COBOL/370. A JCL member is provided to run the job as an MVS batch job on an IBM mainframe or with Micro Focus technologies that support the execution of a mainframe-oriented application running on a Linux, UNIX or Windows platform.

In the world of programming there are many ways to solve a problem. This suite of programs is provided as a COBOL example of a possible solution for producing hexadecimal dump information without an assembler subroutine.

Note: The source code for this example is available from the SimoTime Library under Download Directory at www.simotime.com.


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 1st segment of memory in the preceding hex-dump is identified with a tag of BINTAB01. This is a 256 byte array of one byte elements that includes values from x'00' through x'FF'.

The 2nd segment of memory in the preceding hex-dump is identified with a tag of NBRITEMS. This is a 256 byte group item that contains various numeric values that are stored in memory using a Zoned-decimal, Packed-decimal (COMP-3) and Binary (COMP) format.

Table of Contents Previous Section Next Section The Call Interface

The coding to do an actual call to display and/or log the hex dump information is as follows.

      *****************************************************************
      *    Prepare the Pass Area and call the SIMOHEX1 program.
      *    -----------------------------------------------------------------
           move 'DUMP'                              to SIMOHEX1-REQUEST
           move 'USERINFO'                          to SIMOHEX1-DUMP-ID
           add length of USER-STRING-01 to ZERO giving SIMOHEX1-LENGTH
           CALL 'SIMOHEX1'                       USING SIMOHEX1-PASS-AREA
                                                       USER-STRING-01

Note: In the preceding example the SIMOHEX1-BUFFER is replaced with the name of a user data field.

The call to SIMOHEX1 requires two parameters. The following describes the parameters.

1. SIMOHEX1-PASS-AREA, this is the 1st parameter. It is a group item of four (4) fields.
1.1. SIMOHEX1-REQUEST, this parameter is four (4) chatacters and is case sensitive. It must be upper-case.
1.1.1. DUMP - This parameter value will cause the text string in the SIMOHEX1-BUFFER to be displayed to the SYSOUT device in hexadecimal format. This is the default value.
1.1.2. NOTE - This parameter value will simply post the first 68 bytes in the SIMOHEX1-BUFFER to the SYSOUT device.
1.2. SIMOHEX1-RESULT, this is an indicator as to the success or failure of the request. A value of zero (0000) indicates the routine was successful in displaying the dump information. A non-zero value indicates a failure.
1.3. SIMOHEX1-DUMP-ID, this is an eight character field that is used to identify the dump. When multiple calls are made to the dump routine it is less confusing if each dump request has a unique identifier.
1.4. SIMOHEX1-LENGTH, the length or number of characters to be displayed. This must be a value from 1-128. If a value other than 1-128 is passed then 128 will be assumed.
2. SIMOHEX1-BUFFER, this is the 2nd parameter. It identifies the data string that will be processed by the the Hex-Dump utility (SIMOHEX1). This is a 128 byte buffer containing the information to be posted to the SYSOUT device. This parameter may be replaced by a user-defined data string (or field name).

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
