KBE-Pascal is an interactive programming assistant system. The intention is that the programmer will do the hard parts of design and implementation while the KBE-Pascal will assist him wherever possible. The major underpinning of KBE-Pascal is plan, a kind of representation for programs, which abstracts away from the inessential features of a program and represents the basic logical properties of the algorithm explicitly. The main design goal of KBE-Pascai is rapidly and accurately building up a program by refering to the fragments in the plan library.It's object language is Pascal.The current system is composed of four parts:a coder that can creste program text corresponding to a plan;a library of plans for common algorithm fragments;a plan editor which makes it possible for a programmer to modify a program by modifying its plan;and a text editor which makes it possible for a programmer to edit on program text directly.
