Beatnik

From Esolang

Beatnik is a stack-based esoteric programming language created by Cliff L. Biffle. The code looks like English-language text (typically with sentences that don't make a lot of sense). The words are scored according to the rules of the Scrabble board game, and the score is used to determine the operation.

[edit] Commands

5	Push the next word's value onto the stack.
6	Pop a number from the stack and discard it.
7	Pop two numbers, add them, and push the result.
8	Input a character and push its value.
9	Pop a number and output it as a character.
10	Pop two numbers, subtract the first one popped from the second one popped, and push the result.
11	Pop two numbers, swap them, and push them back.
12	Pop a number and push it twice.
13	Pop a number and skip ahead n (actually n+1) words if the number is zero.
14	Pop a number and skip ahead n (actually n+1) words if the number isn't zero.
15	Pop a number and skip back n words if the number is zero.
16	Pop a number and skip back n words if the number isn't zero.
17	Stop the program.

Any other Scrabble value, interpreted as a command, is a no-op. Note that the commands corresponding to values 5, 13, 14, 15, and 16 each read an extra word and use it as a parameter (then skip it). A value of less than 5 might make the interpreter mock you for your poor Scrabble skills. A value greater than 23 will earn you "Beatnik applause".
