The loop macro in ANSI Common Lisp is anaphoric in binding, where the it expression refers to the result of the test expression in a clause. [2] [3]Here is an example that sums the value of non-nil elements, where it refers to the values of elements that do not equal nil:
Format is a function in Common Lisp that can produce formatted text using a format string similar to the print format string.It provides more functionality than print, allowing the user to output numbers in various formats (including, for instance: hex, binary, octal, roman numerals, and English), apply certain format specifiers only under certain conditions, iterate over data structures ...
Embeddable Common Lisp (ECL) is a small implementation of the ANSI Common Lisp programming language that can be used stand-alone or embedded in extant applications written in C. It creates OS-native executables and libraries (i.e. Executable and Linkable Format (ELF) files on unix) from Common Lisp code, and runs on most platforms that support ...
ECL includes a bytecode interpreter and compiler. It can also compile Lisp code to machine code via a C compiler. ECL then compiles Lisp code to C, compiles the C code with a C compiler and can then load the resulting machine code. It is also possible to embed ECL in C programs, and C code into Common Lisp programs. GNU Common Lisp (GCL)
The Common Lisp HyperSpec is a technical standard document written in the hypertext format Hypertext Markup Language . It is not the American National Standards Institute (ANSI) Common Lisp standard, but is based on it, with permission from ANSI and the International Committee for Information Technology Standards (INCITS, X3).

GNU Common Lisp (GCL) is the GNU Project's ANSI Common Lisp compiler, an evolutionary development of Kyoto Common Lisp. It produces native object code by first generating C code and then calling a C compiler. GCL is the implementation of choice for several large projects including the mathematical tools Maxima, AXIOM, HOL88, and ACL2.
PC-LISP is written primarily in the C programming language, with some parts now also written in Common Lisp. [2] PC-LISP runs well in DOS emulators and on modern Windows versions. Because PC-LISP implements Franz LISP, it is a dynamically scoped predecessor to modern Common Lisp. This is therefore an historically important implementation.
On Lisp: Advanced Techniques for Common Lisp is a book by Paul Graham on macro programming in Common Lisp. Published in 1993, it is currently out of print, [ 1 ] but can be freely downloaded as a PDF file.
