The next few sections of this manual describe the Quintus Objects package in greater detail. In particular, they describe how to define classes, their methods and their slots, and how to reuse class definitions via inheritance. Small sample programs and program fragments are provided for most of the features described.
Experienced Prolog programmers may choose to skip over these sections and look at the sample programs in this package's demo directory, referring to the reference pages as necessary. Everyone is encouraged to experiment with the sample programs before writing their own programs.
