The Orders Program orders.4gl

The orders.4gl module implements the main form controller. Most of the functionality has been described in previous chapters. In this section we will only focus on the DIALOG instruction programming. The program implements a DIALOG instruction, including an INPUT BY NAME sub-dialog for the order fields input, and an INPUT ARRAY sub-dialog for the items input. Unlike traditional 4GL programs using singular dialogs, you typically start the program in the multiple dialog instruction, eliminating the global MENU instruction.
