This is the directory of programs written in INTERCAL. Most of these
are no doubt full of bugs. Don't complain, you're lucky if anything
written in INTERCAL works at all.
Some of these programs are explicitly licenced under the GNU GPL, just
like the C-INTERCAL compiler is; therefore, remember to include
COPYING.txt from the main installation directory if you want to
redistribute these separately from that compiler.
The subdirectory lib contains code fragments that are not complete
programs; the programs in explib are expansion libraries written in C,
which serve as examples of the C-INTERCAL to C interface as well as
potentially being useful.
Programs marked with + have associated .chk files (and, if they take
input, corresponding .tst files) and are part of the regression-test
suite.
Contents:

sample.i Returns absolute value of a 16-bit 2s-complement number
lib/syslib-orig.i Standard library (original buggy version)

random.i Random number program
lib/plus.i Increment .1
by Hans Olsson <f88ho@efd.lth.se>
lib/1910.doc Listing of a random number routine. Hans said he wrote
this because he couldn't find (1910) in the system
library, but it's there in our lib/syslib.i. We keep
this around as an example. (What? Throw away INTERCAL
code? Perish the thought!)
by Louis Howell <nazgul@netcom.com>
life.i Conway's game of Life, standard INTERCAL version
life2.i This version uses COME FROM and character output
blinkers
t_tet
glider
gun Input files for both Life programs
bubble.i + Bubble sort. List of numbers to be sorted must
be preceded with the length of the list.
icat.i + Sends input to output
lib/lib2.i New library routines: decrement, decrement and branch
on 0, add bit, 16-bit division with remainder,
exponentiation
pi.i + Calculate pi to a specified number of digits
primes.i Find prime numbers
pow.i + Prints a list of nth powers using old exponentiation
routine. Expect this to fail with overflow.
lib/syslib.i Corrected version of system library
iching1.i Generates I Ching hexagrams
iching2.i This version uses a lookup table to find the sequence
number
iching.doc Description of the two I Ching programs
change.i Count up different ways to make change
change.doc Description of change.i

comments.

by Jacob Mandelson <jlm@cco.caltech.edu>
rot13.i + Prints ROT-13 of its input
by Jan-Pieter Cornet <johnpc@xs4all.nl>
hail_mary.3i + Print 1,000,000 Hail Marys

tests/iogerunds.i Demonstrate gerund abstention
by Clemens Meier <clmeier@lili.uni-bielefeld.de>
rot13b.i + Another ROT-13 program
By Brian Raiter <breadbox@muppetlabs.com>

lib/syslib7.7i C-INTERCAL's other bases.
lib/syslib3-7.doc Documentation for same
tests/hello.i + The traditional hello world program
ins.i Intersections & Splats, a Mastermind-style game
ins.doc Documentation for I&S
yapp.i + Prints an INTERCAL program that prints
yapp.doc Description of yapp.i
quine.i + Prints itself
lib/floatlib.i Floating-point routines
lib/floatlib.doc Documentation for the floating-point routines
flonck.i + An RPN calculator
flonck.doc Documentation for flonck.i (requires floatlib)
fft.i + Fast Fourier Transform (requires syslib and floatlib)
fft.doc Description of fft.i
by Donald Knuth
tpk.i + Don Knuth's implementation of the TPK algorithm
tpk.doc Don's note about the algorithm
by Oerjan Johansen
unlambda.i + An Unlambda interpreter in INTERCAL
unlambda.doc Better-commented version of the above
by Jeffrey Lee
interfunge.i + A Befunge-93 interpreter in INTERCAL
by Brendan Gregg
guess.i Guessing game implementation in INTERCAL
The subdirectory tests contains some programs written only to test the
compiler.
by David Moews
tests/test1.i + Prints DO THIS TEST HAS BEEN SUCCESSFULLY COMPLETED
tests/test2.i + Reads in two numbers and reports their product
by Alex Smith
tests/ais1.i + Reads in numbers terminated with zero and
writes them back out, testing COME FROM/NEXT
interaction.
tests/ais2.i + A demonstration of computed ABSTAIN's power.
Computes the Fibinacci sequence; in the innput file,
ONE means compute the nextvterm and ZERO means stop.
tests/compucome.i A program to test computed COME FROM
tests/onceagain.i + A single-threaded program testing ONCE and AGAIN.
Output just tracks the program control flow.
tests/arrtest.i A program to test some changes I made to the grammar.
No output expected as it's just a parser test.
tests/arrtest.doc The history behind those changes
tests/permute.i + A permutation-printing program to test backtracking
tests/permute.doc Information about the permutation-printer
tests/whileadd.i + Adds two input numbers with a single WHILE statement
tests/ignorret.i + Testing interactions of IGNORE and RETRIEVE
tests/ignorearray.i + Checking that IGNORE works correctly on arrays
tests/ignorret.doc What ignorret does on several compilers
tests/normaldist.i Checking the standard deviation of (1910)
tests/testcreate.i + A test for the CREATE statement
tests/iffit1.i The INTERCAL side of the INTERCAL/Funge-98 test
tests/iffit2.b98 The Funge side of the INTERCAL/Funge-98 test
tests/iffit.doc Documentation for the INTERCAL/Funge-98 test
explib/syslibc.c The INTERCAL base 2 syslib, optimised version in C
explib/compunex.c An example flow-control routine (computed NEXT)
explib/ecto_b98.c A library that links INTERCAL and Funge-98 code
sort.i + An insertion-sort program testing computed ABSTAIN
continuation.i A continuation library and example program
continuation.doc About usage and internals of the continuation library
by Malcom Ryan
tests/testonce.i + A single-threaded program that tests all permutations
of the ONCE modifier; the output is simply to verify
that the program flow follows the sequence expected.
pass.i + A multithread program illustrating communications
between threads. Simply reads in a list of
numbers (terminated by ZERO) and writes them out.
The programs test16bit.i, testarray.i, testcf.i, testlib2.i, limits.*,
testops*i, were all written by Louis Howell. Of these, testcf.i might
be considered an interesting puzzle---try to figure out what it's
doing. The others are pretty boring, but are included as diagnostics
and because so few other example programs exist. Not all of these
even produce interesting diagnostic output; it may be necessary to
look at the degenerated C code to determine if the compiler is doing
the right thing.
