HyperCard and SuperCard programmers wishing to enhance or go beyond the "card/navigation" model will quickly embrace and feel right at home with easy-to-use, object-oriented CyberDEFs. In these 4GL environs (HyperCard and SuperCard), the native "card" windows are proprietary to the programmers who created them. To use CyberDEFs in such cases, you will, therefore, need to create external windows, dialogs or palettes of your own using a resource editor or just your own code.

If you're just learning to build applications, control panels, and/or external HyperCard windows— CyberDEFs shortens your learning curve in a major way. The amount of knowledge you WON'T have to learn (regarding the life and times of the Mac's Text Edit, List and Control Managers) is massive.

If you can build applications, desk accessories or control panels in C or Pascal, then you certainly skilled enough to use CyberDEFs. AND...CyberDEFs  saves tons of time and hair-pulling by circumventing (to a large degree) the need to continually mess with the List, Text and Control managers. (Did somebody say, "Amen"?)
