- Not to be confused with tom7's ABC (compiler), AlPhAbEt, nor Abc.
ABC is an esoteric programming language created by User:Orange. The language is very simple and easy to implement. This language has nothing to do with the real programming language ABC.
Instructions
a - Increment the accumulator b - Decrement the accumulator c - Output the accumulator d - Invert accumulator r - Set accumulator to a random number between 0 and accumulator n - Set accumulator to 0 $ - Toggle ASCII output mode. When on, the c instruction prints the accumulator as an ASCII character. l - Loop back to the beginning of the program. Accumulator and ASCII mode does not reset. ; - Debug. Prints out accumulator as a number and ascii character.
Unknown instructions are treated as NOPs.
