PROCEDURALLY ORIENTED PROGRAMMING TECHNIQUES IN PROLOG.

A technique for writing Prolog code in a procedural way whenever necessary is presented. x The methods described are based either on relatively simple applications of Prolog facilities or on applications of old concepts, such as structured programming, to Prolog. The efficiency of the code is not the primary concern; the immediate goal is to write something that does the job. Although examples given use numerical values for short and easy demonstration, the technique can be applied to symbolic values represented by atoms, structures, and lists. As with any language, the same task can be written in many different ways in Prolog. The discussion covers developing top-down modules and stubs, common program structures in conventional languages, common data structures, and sequential table processing.
