Naming and Referencing Rules Within HP ALLBASE/4GL, you can name and reference a number of different types of elements. These elements are outlined in the following paragraphs. Developer-Defined Elements In the course of developing an application, you will define names for field specifications, data files, data storage elements, screens, logic elements, and reports. The Communication Area The communication area contains a number of fields that both you and the system can use. These fields have predefined names, although the system administrator can assign one synonym for each communication area field name. Scratch-Pad Fields HP ALLBASE/4GL allows you to use up to 100 scratch-pad fields for temporary data storage. Each scratch-pad field takes on the attributes (length, edit code and justification) of the data moved into it. HP ALLBASE/4GL allocates memory for scratch-pad fields dynamically, minimizing the application's demands on system memory. This means that using scratch-pad fields may be more efficient than using variables.
