HP ALLBASE/4GL Developer Self-Paced Training Guide

Defining the Logic for the Training Application 

The logic blocks you are about to define specify how the application
displays the product_scrn screen and how the data entered on the screen
is handled.

For the KSAM and HP TurboIMAGE/iX based applications, the logic blocks
allow you to add data to the product file, or modify existing data in the
file.

For the HP ALLBASE/SQL based application, the logic blocks allow you to
add data to the product file, or view existing data in the file.

The logic blocks for the training application are:

   *   A process, called from the menu, to control the screen and the
       manipulation of the data file.

   *   A function, called from a data screen, to check for the existence
       of the record requested by the user.

   *   For HP ALLBASE/SQL applications, an SQL logic block to declare and
       open a cursor in the HP ALLBASE/SQL table, and an SQL logic block
       to commit data.

The logic blocks have been kept as simple as possible so you can get a
basic file manipulation system running quickly.
