Application Properties  Repository Inquiry and Update using CICS

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

This example uses a a suite of COBOL programs and BMS mapsets to display a screen that will prompt a user for a source member name. Once a source member name is entered the program will access the Application Properties Repository (APMASTER is a VSAM, KSDS). The programs use command level CICS statements to access APMASTER 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.

Display Source Member Properties
(Next) (Previous) (Table-of-Contents)

To display the Application Properties screen a COBOL program and a BMS screen is used. The Application Properties Screen contains a prompt for a new Source Member Name and the source member information from a previous request. Once a new source member name is entered the Application Properties Repository is accessed and the new information is displayed. Various EXEC CICS commands are used to access the repository and re-display the screen.

Application Properties Repository
(Next) (Previous) (Table-of-Contents)

The Application Properties Repository is a VSAM, Key Sequenced Data Structure (or KSDS). It has a record length of 1,024 bytes with a 18 byte key starting in position 1 of the record. The following copy file (APMASTB1.CPY) shows the record structure.
