INTERCAL

Basic INTERCAL Resources

• The C-INTERCAL Distribution
  This includes the compiler, full documentation, and most known INTERCAL programs. Maintained by Eric S. Raymond, the author of the C-INTERCAL compiler.
• The HTML Version of the C-INTERCAL Manual
  Complete and up-to-date.
• The INTERCAL Resources Page
  Eric S. Raymond's links to the essential INTERCAL resources.
• The Original INTERCAL Manual
  This text file is how the legend of INTERCAL spread to the outside world.
• The Pit
  From here you can download individual INTERCAL programs. Also includes an analysis of an exponentiation routine. Maintained by Louis Howell, a master INTERCAL programmer.
• Jacob Mandelson's INTERCAL Page
  Another accomplished INTERCAL programmer.
• What is INTERCAL?
  If you don't know what INTERCAL is, this introduction will not help you in the slightest.
• Useful Tables
  (Relatively speaking.) A collection of tables relevant to writing INTERCAL programs.
• alt.lang.intercal
  A quiet newsgroup with irregular propogation and the occasional burst of activity.

Other INTERCAL implementations

• Karsten Sperling's J-INTERCAL Page
  Not content with having the INTERCAL compiler available only on Unix, Karsten Sperling has written an implementation for the Java virtual machine.
• William Walter Patterson's INTERCAL Page
  William Walter Patterson did the strangely appropriate port of the C-INTERCAL 0.15 compiler to MS-DOS (endorsed by the author). From his page you can download the latest version.
• C-INTERCAL for OS/2 diff file
  Yes, C-INTERCAL is also available for OS/2, with EMX and GCC installed. This file indicates the minor changes that need to be made in the src directory before building.
• Assurdo Technologies
  Assurdo Technologies wisely understand that INTERCAL is the key to world domination. Not content to let the original language gather moss, their CLC-INTERCAL (compiles to Perl) offers many new and bizarre features.
• INTERCAL Operators in Perl
  For the polyglot hacker: adding the INTERCAL operators to Perl.
• calc-intercal.el
  An extension to Emacs' calculator mode that implements the INTERCAL operators, written by Jon Ferro. (Archived by Eric S. Raymond.)

Brian Raiter's INTERCAL Programs

• "Numerical" I/O Library
  This is an INTERCAL library of useful I/O routines, including some for doing numerical I/O.
• Intersections & Splats
  The world's first INTERCAL CGI script. Written entirely in INTERCAL, this script allows you to play a Mastermind-style game with your web browser. Instructions are on the starting page. Intersections & Splats also exists as a standalone game; the current distribution contains documentation and a colorized version of the game (for vt100/ANSI-style color terminals only).
• Yapp
  An INTERCAL program that generates INTERCAL programs.
• A Quine for C-INTERCAL
  They said it couldn't be done. (They were wrong.) They also said it shouldn't be done. (No comment.) In any case, quine.i is an INTERCAL program which, when executed, produces its own source code. This page explains how it works.
• syslib.3i through syslib.7i
  New ports of the standard library for the non-binary dialects of C-INTERCAL. All the standard library functions are supported, for each of the bases 3 through 7.
• The Floating-Point Package
  The big one. This package includes a complete floating-point library, a Fast Fourier Transform program, and flonck, an RPN calculator.
• An INTERCAL Puzzle
  Try to figure out what the purpose of this program is.

Miscellaneous Sightings

• The Retrocomputing Museum
  A fascinating collection of resurrected compilers, interpreters, and miscellanea that would otherwise be forgotten, sometimes deservedly so.
• A Recursive Benchmark in Fourteen Languages
  Louis Howell carefully analyzes how several different languages fare at optimizing (and/or just plain implementing) a classic recursive algorithm. C, C++, Lisp, INTERCAL, Orthogonal, Algol, Ghostscript, and others.
• Cat's-Eye Technologies
  Chris Pressey maintains a website devoted to "esoteric topics in computer programming". In other words, a clearinghouse for weird programming languages.
• Hello World in INTERCAL
  This page catalogues the hello world program in many different languages.
• Bottles of Beer in INTERCAL
  This page, on the other hand, catalogues programs that sing the "99 Bottles of Beer" song in many different languages.
• The Quine Page
  Here we have a list of known quines in several different languages, collected by Gary Thompson.
• The TPK program in INTERCAL
  Here you can see how Knuth translated his TPK program into idiomatic INTERCAL. (If you've never heard of the TPK program, read more about it here.)
• "Abstraction and Modularity in INTERCAL"
  D. Alexandar Garrett wrote this analysis of INTERCAL for a class on Programming Theory and Design, apparently to the detriment of his GPA and sanity. (Archived by Eric S. Raymond.)
• Charlie Stross on INTERCAL
  Finally here is an archive of a 1992 Computer Shopper article on INTERCAL. Although it contains a few glaring errors, nonetheless it is well-written, and a rare appearance of INTERCAL in the print media - perhaps the only one outside of The New Hacker's Dictionary.
