Menu for Files and VSAM Access to non-Relational Data |
|
| The SimoTime Home Page |
Introduction
This example uses a COBOL programs and a BMS mapset to display a menu screen and transfer control to programs that will perform various data file inquiry or update functions. The programs use command level CICS statements and display information to a 3270 terminal or terminal emulator. The programs run on an IBM Mainframe System with CICS or a Microsoft Windows System with Micro Focus Server for Mainframe Migration.
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.

Menu Options, File & VSAM Access
The main menu provides links to the data file inquiry and update programs for the Customer Master File and the Item Master File plus a link to the menu for additional utility programs. The transaction identifier (or Tran ID) to display the main menu is "OPT1" and the program is "MN1FMS". The following shows the main menu screen.

The following sections provide a brief description of the transaction definitions associated with the Main Menu options.
1. Customer Data File Inquiry
The transaction identifier (or Tran ID) for this menu option is "CUI1" and the program is "CU2INQ". This program will prompt a user for the customer number. Once a customer number is entered the program accesses the Customer Master File (CUSTMAST) and displays the customer information at the 3270 Terminal. If a customer record is not found a message is displayed. A user may continue to enter customer numbers or exit the program. This program is part of the zPACK for Data File Management.
Review the Documentation for this suite of program members. Link to an Evaluation zPAK Option that includes the program members, documentation and control files.
2. Item Data File Inquiry
The transaction identifier (or Tran ID) for this menu option is "ITI1" and the program is "IT2INQ". This program will prompt a user for the item number. Once a item number is entered the program accesses the Item Master File (ITEMMAST) and displays the item information at the 3270 Terminal. If a item record is not found a message is displayed. A user may continue to enter item numbers or exit the program.
Review the Documentation for this suite of program members. Link to an Evaluation zPAK Option that includes the program members, documentation and control files.
3. Customer Data File Update
The transaction identifier (or Tran ID) for this menu option is "CUU1" and the program is "CU2UPD". This program will prompt a user for the customer number. Once a customer number is entered the program accesses the Customer Master File (CUSTMAST) and displays the customer information at the 3270 Terminal. A user may update the record or continue to enter customer numbers or exit the program. If a customer record is not found a message is displayed. This program is part of the zPACK for Data File Management.
Review the Documentation for this suite of program members. Link to an Evaluation zPAK Option that includes the program members, documentation and control files.
4. Item Data File Update
The transaction identifier (or Tran ID) for this menu option is "ITU1" and the program is "IT2UPD". This program will prompt a user for the item number. Once an item number is entered the program accesses the Item Master File (ITEMMAST) and displays the item information at the 3270 Terminal. A user may update the record or continue to enter item numbers or exit the program. If an item record is not found a message is displayed. This program is part of the zPACK for Data File Management.
Review the Documentation for this suite of program members. Link to an Evaluation zPAK Option that includes the program members, documentation and control files.
8. Return to Main Menu
The transaction identifier (or Tran ID) for this menu option is "MM01" and the program is "MN1APP". This program will display the Main Menu at the 3270 Terminal. For additional information refer to the Main Menu Screen or primary menu.
9. End of Job, Sign Off
This will end the application and display the CICS transaction screen.

Summary
The purpose of this suite of program is to provide examples that use command level CICS in COBOL programs to access VSAM, Key-Sequenced-Data-Sets (KSDS) and display the information using standard BMS screen definitions to a 3270 terminal or terminal emulator. This document may be used as a tutorial for new programmers or as a quick reference for experienced programmers.
In the world of programming there are many ways to solve a problem. This documentation and software were developed and tested on systems that are configured for a SIMOTIME environment based on the hardware, operating systems, user requirements and security requirements. Therefore, adjustments may be needed to execute the jobs and programs when transferred to a system of a different architecture or configuration.
SIMOTIME Services has experience in moving or sharing data or application processing across a variety of systems. For additional information about SIMOTIME Services or Technologies please contact us using the information in the Contact or Feedback section of this document.

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
