Demonstration application - BLDRAPPL

The demonstration application provided for this tutorial is a basic, online application named BLDRAPPL. It is missing some components that you define in AppMaster Builder.

BLDRAPPL uses CICS/VSAM as the development target because it is commonly used in production.

The BLDRAPPL application performs the following functions:

  • Presents a selection menu
  • Enables you to add, update, query, and delete records
  • Calculates the total value of your inventory
  • Provides an exit

The application as shipped includes two programs and associated screens:

BLDRCMNU program
BLDRCMNU is a menu program that interacts with the BLDRCM screen.
BLDRCM screen
Provides access to two program screens, and provides an option to exit the application.
Main Menu Screen
BLDRCADD program
BLDRCADD interacts with the BLDRCA screen.
BLDRCA screen
Enables your end user to add parts information and records to a database, and then return to the main menu.
