From Esolang
AlphaBeta is a language made by User:Voxel and only uses letters as instructions.

[edit] History
AlphaBeta was created by User:Voxel in early 2009 in an attempt to make a language that was easy to write, and had many instructions. The language was also made as an experiment and a test of skills.
[edit] Specification and Instruction List
AlphaBeta uses 5 registers as a way to store memory, 2 are changeable and hold an integer, 1 is a result register and cannot be changed, 1 is used for looping and the other is used for memory ( like brainfuck's > and < ). There is no way of comments. Also, AlphaBeta has 1 kb of ram.
There are 52 instructions:
a adds 1 to register 1 b subtracts 1 from register 1 c adds 10 to register 1 d subtracts 10 from register 1 e adds 100 to register 1 f subtracts 100 from register 1 g adds 1 to register 2 h subtracts 1 from register 2 i adds 10 to register 2 j subtracts 10 from register 2 k adds 100 to register 2 l subtracts 100 from register 2 m sets register 3 to the logical not of register 1 n sets register 3 to the logical not of register 2 o logical ands register 1 and register 2 and sets register 3 to the result p logical ors register 1 and register 2 and sets register 3 to the result q logical xors register 1 and register 2 and sets register 3 to the result r adds register 1 and register 2 and sets register 3 to the result s subtracts register 1 and register 2 and sets register 3 to the result t multiplies register 1 and register 2 and sets register 3 to the result u divides register 1 and register 2 and sets register 3 to the result v mods register 1 and register 2 and sets register 3 to the result w register 3 to register 1 to the power of register 2 x clears register 1 y clears register 2 z clears register 3 A sets register 2 to the value of register 1 B sets register 1 to the value of register 2 C sets register 3 to the value of register 1 D sets register 3 to the value of register 2 E sets register 1 to the value of register 3 F sets register 2 to the value of register 3 G sets register 1 to the memory at the memory pointer H sets register 2 to the memory at the memory pointer I sets the memory at the memory pointer to the value of register 3 J input a value from the keyboard and store it in register 1 K input a value from the keyboard and store it in register 2 L outputs a character to the screen M outputs a number to the screen N if register 1 equals register 2, goto the position at the position register O if register 1 does not equal register 2, goto the position at the position register P if register 1 is bigger than or equals register 2, goto the position at the position register Q if register 1 is smaller than or equals register 2, goto the position at the position register R if register 3 equals 0, goto the position at the position register
The memory pointer and the position pointer are 2 different things, but you change them through 1 register. ( The Z command switches between them.)
S adds 1 to the register T subtracts 1 to the register U adds 10 to the register V subtracts 10 to the register W adds 100 to the register X subtracts 100 to the register Y sets the register to 0 Z switches in-between modes ( starts on memory pointer )

- Interpreter written in C++ by User:Voxel. It has a problem with input which I will look into.
