What is The Difference Between Janus And RPG, Programming Languages

What are Logic-based Programming Languages
Logic programming is a type of programming paradigm which is largely based on formal logic. Any program written in a logic programming language is a set of sentences in logical form, expressing facts and rules about some problem domain. (Wikipedia)
What are Procedural Programming Languages
Procedural (imperative) programming implies specifying the steps that the programs should take to reach to an intended state. A procedure is a group of statements that can be referenced through a procedure call. Procedures help in the reuse of code. Procedural programming makes the programs structured and easily traceable for program flow.
