FormPlus: A form authoring toolkit

The authors present the design and implementation of FormPlus, a form authoring toolkit for on-screen form design and filing. It is implemented on an IBM OS/2 Presentation Manager platform. FormPlus provides major front-end functions for form processing such as converting paper forms into electronic forms, designing forms, and filling in forms. No knowledge about programming is necessary. FormPlus also provides an object-oriented API (Application Programming Interface) for programmers to develop their own applications with minimum effort. FormPlus is designed to be easily extendable to incorporate new objects and to allow data import and export.
