LISP 1.5 Programmer's Manual

摘要: The LISP language is designed primarily for symbolic data processing used calculations in differential and integral calculus, electrical circuit theory, mathematical logic, game playing, other fields of artificial intelligence.The manual describes LISP, a formal language. differs from most programming languages three important ways. first way the nature data. In language, all are form expressions usually referred to as S-expressions, indefinite length, which have branching tree-type structure, so that significant subexpressions can be readily isolated. system, bulk available memory storing S-expressions list structures. second distinction source itself specifies what processed. Third, interpret execute programs written S-expressions. Thus, like machine unlike high level languages, it generate further executions.
