Unorthodox Programming Languages
Brainf*** is a programming language that is so simple, it's hard!
It only has eight commands, in the form of eight ASCII characters. They are:
- >
- increment the data pointer (to point to the next cell to the right).
- <
- decrement the data pointer (to point to the next cell to the left).
- +
- increment (increase by one) the byte at the data pointer.
- -
- decrement (decrease by one) the byte at the data pointer.
- .
- output the byte at the data pointer.
- ,
- accept one byte of input, storing its value in the byte at the data pointer.
- [
- if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command.
- ]
- if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command.
Here is an example program, the classic "Hello World!" program.

LOLCODE is Cheezburger as a programming language, basically. Its homepage: lolcode. com .
Here is the classic "Hello World!" program in LOLCODE.
HAI
CAN HAS STDIO?
VISIBLE "HAI WORLD!"
KTHXBYEI have no idea how LOLCODE works. Please look into that.
Can you think of other unorthodox programming languages?
