Datasets and Form Fields
You create forms and their fields with the ABF FormEdit operation. When 4GL retrieves data from a table in the database into the simple fields or the table field on a form, it stores the rows of retrieved data in a temporary structure known as the dataset for the form. Because only a limited number of retrieved records can be displayed in the window at a time, 4GL holds any remaining records in a buffer.
• In the simple fields of a form, one record in the data set is displayed at a time. Succeeding records can be viewed using the next statement with an attached menu.
• In the table field of a form, all records are loaded into the table field. Several records are visible at once in the rows of the table field. You can view any succeeding records of the dataset by scrolling through the table field with the cursor control keys.
