(ProKappa is a modern, multi-paradigm knowledge-based\u2013system development tool. It includes facilities for dynamic object management, rule-based processing, daemons, and graphical developer and end-user interfaces. ProKappa is a successor system to KEE.) Creating PrkAda required creating a run-time, Ada-language, object-system \"core,\" and developing a compiler to Ada from ProTalk (ProKappa's high-level, backtracking-based language). We describe PrkAda ProTalk compiler in a companion paper [5].
