File Management Application  CICS Application running with Micro Focus http://www.simotime.com

Introduction
(Next) (Previous) (Table-of-Contents)

This example uses a a suite of COBOL programs and BMS map sets to execute programs that will provide data file inquiry or update functionality. 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.

Menu Program
(Next) (Previous) (Table-of-Contents)

To display a menu of options on the screen a COBOL program and a BMS screen is used. The Menu Screen contains a list of options. Once an option is selected an EXEC CICS LINK is used to pass control to the appropriate program and perform the requested function.

Data File Management
(Next) (Previous) (Table-of-Contents)

The Files used in this suite of sample programs were created from batch jobs. The master files are VSAM, Keyed-Sequential-Data-Sets (KSDS). The VSAM clusters are defined using IDCAMS. A batch job that executes a COBOL program is used to initially add records to the VSAM data sets.

Customer Master File
(Next) (Previous) (Table-of-Contents)

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 is the COBOL copy file that defines the record layout.

Customer Master File, Inquiry Program
(Next) (Previous) (Table-of-Contents)

The following program (CU2INQ.CBL) is a CICS program that will provide viewing (or inquiry) access to the Customer Master File. By typing a customer number a record will be retrieved and displayed to the screen using standard Basic Mapping Support (BMS) techniques. For more information refer to the  Customer File Inquiry that is provided in a separate document.
