The following Comparison of Prolog implementations provides a reference for the relative feature sets and performance of different implementations of the Prolog computer programming language. A comprehensive discussion of the most significant Prolog systems is presented in an article published in the 50-years of Prolog anniversary issue of the ...
CAD data exchange is a method of drawing data exchange used to translate between different computer-aided design authoring systems or between CAD and other downstream CAx systems. [ 1 ] : 157 Many companies use different CAD systems and exchange CAD data file format with suppliers, customers, and subcontractors. [ 2 ]
Operationally, Prolog's execution strategy can be thought of as a generalization of function calls in other languages, one difference being that multiple clause heads can match a given call. In that case, the system creates a choice-point, unifies the goal with the clause head of the first alternative, and continues with the goals of that first ...

In some cases this is importing the exported functionality of a library, package or module but some mechanisms are simpler text file include operations. Import can be classified by level (module, package, class, procedure,...) and by syntax (directive name, attributes,...). File include
Among other differences between logic and rules, he argues that logic uses deduction, but rules use search (page 45) and can be used to reason either forward or backward (page 47). Sentences in logic "have to be interpreted as universally true ", but rules can be defaults , which admit exceptions (page 44).
AutoLISP is a small, dynamically scoped, dynamically typed Lisp language dialect with garbage collection, immutable list structure, and settable symbols, lacking in such regular Lisp features as macro system, records definition facilities, arrays, functions with variable number of arguments or let bindings.
The general format of EDIF involves using parentheses to delimit data definitions, and in this way it superficially resembles Lisp.The basic tokens of EDIF 2.0.0 were keywords (like library, cell, instance, etc.), strings (delimited with double quotes), integer numbers, symbolic constants (e.g. GENERIC, TIE, RIPPER for cell types) and "Identifiers", which are reference labels formed from a ...
