User:ScallopMonger/AAAAAAAAAAAAAA!!!!
AAAAAAAAAAAAAA!!!! is an esoteric programming language expressed entirely by the letter A, spaces, commas, and exclamation points. Because of the limited set of characters used, it can be difficult to find the beginning and end of expressions. AAAAAAAAAAAAAA!!!! was first developed in 2006.

| AAAA AAA, n! | Decrement value at index n unless value is zero |
| AAAA, A n! | Set command change register to n |
| AAAA, AA A n! | Change all commands in program that start with what is in command change register to start with n instead |
| AAAA, AA AAA n! | Change all commands in program that end with what is in command change register to end with n instead |

Operators
[edit]| AAAA | number 0 |
| AAA | number 1 |
| A | number 2 |
| AA A | number 3 |
| AAAA A | last index number read by a previous command |
| AAAAA, n | value at index n |
| AA A, a b | a + b |
| AA AA | a b = abs(a - b) |
| AAA | a b = a * b |
| AA AAA | a b = a AND b |
| AAAA | a b = a XOR b |
| AAAAAA n a b | Call subroutine n with parameter a and b, and return value |
