+  [anagram.bf](anagram.bf)               Kalyna Zazelenchuk    1/1/93     This program will input a string of sixteen characters or less, and (p)ut those characters in order on line 3 (the line with the \*'s). It will then randomly find numbers from 1 to 16, (g)et the characters at line 3 in random order, replace them with \*'s, and print them out. Effectively produces anagrams of words you type in. It uses the code from 'rand2.bf' to generate random numbers.

+
+  [befbef2.bf](befbef2.bf)     CC0       Wim Rijnders          ?/?/00     A version of befbef.bf with some bugs (pointed out by Amir Karger) fixed.

+
+  [calc.bf](calc.bf)                     Bryan L               4/10/97    This is a befunged calculator. Meaning ".", the print command, will also pop the result off the stack. Fortunately, the duplication command ":" is supported. This calculator will blithely ignore anything that isn't a number or a supported command. The list of commands is found on line 3.
+
+  [cascade.bf](cascade.bf)     CC0       Chris Pressey         7/20/97    Like copyme.bf, but continues to replicate itself.

+
+  [ea.bf](ea.bf)               CC0       Chris Pressey         1/1/93     Makes 'enigmatic aphorisms.' A loose interpretation of a program in '1001 things to do with your Commodore 64.' This is an example of how to simulate a 'gosub' with a value.
+
+  [easm.bf](easm.bf)           CC0       Chris Pressey         1/1/93     Same as 'ea.bf', but uses self-modifying code.

+
+  [fact.bf](fact.bf)           CC0       Chris Pressey         1/1/93     Asks for a number, and supplies the factorial of that number.
+
+  [fact2.bf](fact2.bf)                   Jason Reed            5/18/97    Factorial generator, (3x12)

+
+  [hello.bf](hello.bf)         CC0       Chris Pressey         1/1/93     The ubiquitous "Hello, World!" program.
+
+  [hex.bf](hex.bf)             CC0       Chris Pressey         1/1/93     Translates ASCII input into hex output.
+
+  [hwii.bf](hwii.bf)           CC0       Chris Pressey         1/1/93     Prints out "Hello, World!' forwards, then backwards, then forwards, etc. Demonstrates how one can so easily change the direction of the PC to support their own wicked desires.
+
+  [kmquine.bf](kmquine.bf)               Keymaker              9/3/08     The first of a series of really fine quines (self-printing programs) by Keymaker.
+

+
+  [madd.bf](madd.bf)                     Greg Wright           6/5/97     3x3-Matrix Addition
+
+  [mandel.bf](mandel.bf)                 Chris Lahey           4/11/97    A Mandelbrot fractal generator.
+
+  [maze.bf](maze.bf)           CC0       Chris Pressey         1/1/93     A conversion of a Commodore-64 graphical pastime: a dead-simple random maze generator.
+
+  [namegame.bf](namegame.bf)   CC0       Dmitry M Litvinov     2/1/96     "First, example easy writed stupid prog." Befunge bypasses cultural and lingual backgrounds. Try this "easily written" program and see what it does.
+
+  [numer.bf](numer.bf)         CC0       Chris Pressey         1/1/93     Produces single-digit numerological equivalents of words you type in. (Users should be warned that the significance of the output of this program is of extremely questionable practical value. But it is consistant.) (This algorithm is also known as the "digital root".)
+
+  [pairing.bf](pairing.bf)               Aaron Dale            3/20/97    A program to implement the "pairing function" (\<x1,x2\> = (2\^(x1) \* (2\*(x2) + 1)) - 1), which maps any two natural numbers onto the set of natural numbers, without repetition.
+
+  [pangram.bf](pangram.bf)     CC0       Chris Pressey         8/25/12    Checks if the first line of input is a pangram -- a sentence which contains all the letters of the alphabet, such as "The quick brown fox jumps over the lazy dog" or "Pack my lunch box with five dozen liquor jugs." Case-insensitive, and ignores most punctuation, but "high" punctuation (above ASCII character 90) will likely confuse it.
+
+  [pascserp.bf](pascserp.bf)   CC0       Chris Pressey         7/12/97    Generates a gasket (Serpinsky triangle) using Pascal's Triangle.

+
+  [pi2.bf](pi2.bf)                       Kevin Vigor           7/2/97     Generates the first hundred digits of Pi. It does this not by cheating, but actually calculating Pi; unfortunately it far exceeds 100 characters of Befunge code.
+
+  [prime.bf](prime.bf)                   Kalyna Zazelenchuk    1/1/93     Lists the counting numbers incrementally from one and checks if each is prime.
+
+  [rand.bf](rand.bf)                     Chris Pressey         1/1/93     Generates random numbers between 1 and 9 as statistically evenly distributed as the computer's random number generator.
+
+  [rand10.bf](rand10.bf)                 Ken Bateman           4/12/97    A 3x10 random number generator.
+
+  [rand11.bf](rand11.bf)                 Ken Bateman           4/12/97    A 5x7 flexible random number generator. The number of bits is set with the 88+ at the top left. As shown this program will generate a random number from 0 to 32767.
+
+  [rand12.bf](rand12.bf)                 Ben Olmstead          4/24/97    A 2x13, 0..255 random number generator.

+
+  [rand14.bf](rand14.bf)                 Greg Wright           5/18/97    4x7 random number generator.
+
+  [rand15.bf](rand15.bf)                 Artyom Baranov        4/5/96     THE smallest Befunge RNG-16. (16x1)
+
+  [rand2.bf](rand2.bf)                   Kalyna Zazelenchuk    1/1/93     This program, crammed into a 14x14 block, makes random numbers from 1 to 16 using multiple "?" statements.
+
+  [rand3.bf](rand3.bf)                   Chris Pressey         1/1/93     12x9 random number generator, like rand.bf and rand2.bf.
+
+  [rand4.bf](rand4.bf)                   Matthew D Moss        2/1/96     A 7x7 random number generator in the tradition of rand.bf .. rand3.bf, but using mathematics to reduce the problem before writing the code
+
+  [rand5.bf](rand5.bf)         CC0       Dmitry M Litvinov     2/1/96     A 4x10 random number generator which produces the same output as rand.bf .. rand4.bf. Unlike most Befunge sources this one has a symmetrical beauty to it.
+
+  [rand6.bf](rand6.bf)                   Artyom Baranov?       12/1/96    An 8x4 random number generator a la rand5.bf.
+
+  [rand7.bf](rand7.bf)                   ???                   12/1/96    A 13x3 random number generator a la rand5.bf and rand6.bf.
+
+  [rand8.bf](rand8.bf)                   Chris Howe            4/9/97     A 4x9 flexible random number generator; if you change the 4 in position (1,2) to another integer n it will generate a number between 1 and 2\^n (inclusive) for 0\<n\<9.
+
+  [rand9.bf](rand9.bf)                   Chris Lahey           4/11/97    A 3x7 random number generator.
+
+  [rdp.bf](rdp.bf)             CC0       Dmitry M Litvinov     2/1/96     A command-line calculator with postfix notation.
+
+  [rdp2.bf](rdp2.bf)                     Kimberley Burchette   12/1/96    A version of rdp.bf crammed into a 23x12 block.
+
+  [robot.bf](robot.bf)         CC0       Chris Pressey         1/1/93     You control an 'O' going through a maze of '\*''s. You can type in 'n', 's', 'e', or 'w', and the 'O' travels in that map direction. This not-particularly-challenging game ends when you hit a '\*'.
+
+  [rot13.bf](rot13.bf)                   ???                   9/11/97    Performs the rot13 algorithm.
+
+  [selflis2.bf](selflis2.bf)   CC0       Chris Pressey         12/1/96    A self-reproducing 80x1 program. This program can also be used to test for the @ vs StringMode bug.

+
+  [selflis6.bf](selflis6.bf)             Denis Moskowitz       5/8/97     14-byte quine.
+
+  [selflist.bf](selflist.bf)             ???                   12/1/196   A self-reproducing Befunge program, 13x4.
+
+  [serp.bf](serp.bf)                     Kevin Vigor           4/9/97     Generates and prints a Serpinsky triangle, a simple type of fractal. Since the resolution is 20x30, the detail of the fractal isn't really visible, but hey, what can you do?
+
+  [serp2.bf](serp2.bf)                   Kevin Vigor           4/10/97    Improved Serpinsky Triangle generator.

+
+  [sort.bf](sort.bf)                     Kalyna Zazelenchuk    1/1/93     Same as anagram.bf, except sorts the letters of your word in ascending order.
