  2. LISP (List processing ) • The use of parentheses is Lisp's difference from other programming language families. As a result, students have long given Lisp nicknames such as Lost In Stupid Parentheses

  3. SBCL • Steel Bank Common Lisp is a free Common Lisp implementation that features a high performance native compiler, Unicode support and threading.

  4. LISP • Lisp is the second-oldest high-level programming language in widespread use today. • Lisp was originally created as a practical mathematical notation for computer programs,  • Lisp pioneered many ideas in computer science, including tree data structures,  higher-order functions, recursion, and the self-hosting compiler

  5. Connection to artificial intelligence • Lisp was closely connected with the artificial intelligence research community, especially on PDP (product development process ) systems. Lisp was used as the implementation of the programming language Micro Planner which was used in the famous AI system SHRDLU.

  6. Advantages of LISP • Common Lisp is  • a general-purpose programming language and an AI language • interactive  • Common Lisp programs are  • easy to test (interactive)  • easy to maintain (depending on programming style)  • portable across hardware/OS platforms and implementations (there is a standard for the language and the library functions) 

  7. Common Lisp provides  • clear syntax, carefully designed semantics  • several data types: numbers, strings, arrays, lists, characters, symbols, structures, streams etc.  • many generic functions: 88 arithmetic functions for all kinds of numbers (integers, ratios, floating point numbers, complex numbers), automatic memory management (garbage collection)  • packaging of programs into modules  • macros: every programmer can make his own language extensions 

  8. Operators • Arithmetic operators are treated similarly. The expression • evaluates to 10. The equivalent under infix notation would be (+ 1234) •  "1 + 2 + 3 + 4"
