Using the Module Builder Screen You are now ready to use the module builder to build the resultant screen and associated logic needed to allow users to access the order file. To access the module builder screen, choose Module Builder from the main menu. HP ALLBASE/4GL displays the module builder screen shown below.Module Builder Screen Description You use the module builder screen to specify the essential information required by the module builder to create the order module. This screen requires you to specify the main file name, along with a record layout name and an index field name. The module uses the specified record layout and index field to access the main file. To enter the field values: Field Entry Explanation --------------------------------------------------------------------------------------- Module Name order This name is used by the module builder in the names it gives most application items it creates for the module. The naming conventions used by the module builder are described in the HP ALLBASE/4GL Developer Reference Manual. Type Accept the default of There are two possible module types: M. maintenance and inquiry. A maintenance type module allows the end user to view and modify the information in the file. An inquiry type module only allows the end user to view the file. Main Access: File order This field specifies the file you defined earlier as the main file to be accessed by the module for viewing or maintenance. Record Accept the default. This is the record layout used to access the file. HP ALLBASE/4GL automatically enters the default record layout. This field is bypassed for HP ALLBASE/SQL tables, because each table can only contain one record layout. KSAM files and HP TurboIMAGE/iX data sets may contain more than one record layout. If you are developing your application based on either of these data managers, accept the default value of order. Table 8-0. (cont.) Field Entry Explanation --------------------------------------------------------------------------------------- Index Accept the default of This is the name of the field used to order_no. locate an individual record within a file. This value defaults to the primary index for the file. Include All Fields Accept the default of This tells the module builder to include Y. all fields listed in the record layout in the resultant screen. If you enter N, you must use the module details screen to define which fields from the record lafuyout you want in the resultant screen. The module builder always includes the index field in the resultant screen. To complete and commit the screen: 1. Press the Commit Data function key when you have completed the module builder screen. HP ALLBASE/4GL displays a message asking you either to specify details on the module details screen or to generate the module. _________________________________________________________________ NOTE At this point you could generate the module, provided you specified Y at the Include All Fields prompt. Module builder would attempt to place all the fields in the record layout on the resultant screen, and there would be no links to secondary files. However, in this lesson you will access the module details screen to add the links to the secondary file. _________________________________________________________________ 2. Press the Specify Details function key to display the module details screen.
