Customer Master File
CICS, Inquiry & Update of VSAM
|The SimoTime Home Page|
This example uses a suite of COBOL programs and BMS mapsets to execute programs that will provide data file inquiry or update functionality for the Customer Master File. The programs use command level CICS statements to access the VSAM Master Files 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.

The Customer Master Inquiry Screen contains a prompt for a new Customer Number and the customer information from a previous request. Once a new customer number is entered the Customer Master File is accessed and the new information is displayed.

The Customer Master File is a VSAM, Key-Sequenced-Data-Set (KSDS). The length of the records in the data set is 512 bytes. The key field starts in position one (1) and is 12 bytes in length. The following (CUSTCB01.cpy) is the COBOL copy file that defines the record layout.

We appreciate hearing from you.
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
