5.2.2 Programming Language
LPA Win-Prolog Programming.
Prolog is a language, which is completely different from other languages normally used
in the programming of computers. The programming languages BASIC, C and PASCAL
are languages which use, as their main technique in programming, a method of splitting a
problem into discrete steps and obeying those steps in sequential order. That is, the
programming language exactly mimics the way in which a digital computer obeys the
programmed commands. Each machine instruction is a discrete step giving an exact
order to the computer and the computer carries the instruction out exactly. Each
instruction is obeyed and the actions are irrevocable. The computer stores information in
its memory overwriting the previous contents. These kinds of languages are called
algorithmic languages. An algorithm is a mathematical procedure, which enables a
problem to be solved by a finite number of steps. Algorithmic languages are those
languages, which are designed to provide solutions by expecting a problem to be divided
into a number of discrete steps. Prolog is not considered to be an algorithmic language.
The name Prolog comes from Programming in Logic. Prolog is not in fact
considered to be a true logic programming language but it is definitely a great step in the
right direction towards producing a logic programming language. Prolog is a very
attractive language for professionals in the area of Knowledge Engineering and Artificial
