Form fields

Form fields are form elements designed for data input and/or data display.

A form field is a form item dedicated to data management. It associates a form item with a screen record field.

A form field defines an area where the user can view and edit data, depending on its description in the form specification file and the interactive statements in the program.

The interactive instruction must mediate between screen record fields and database columns by using program variables.
