((?)?)? is an esoteric programing language made by User:Mipinggfxgbtftybfhfyhfn.

Memory Structure

In ((?)?)? there are three loctaions to store data:

  • The bit (a bit used for all the operations are made)
  • The stack (a group of bits used to store more complex data)
  • The variable system (a group of bits, each asigned to its own name, used for saving data in a structured way)

All the data is stored as a bit.



A group is a code block which is executed with its own bit (initialized at 0). After the group ends, its bit is stored into the main bit, or if the group is nested, the bit is stored in the bit of the outer group. A program can be considered a group were all the instructions are executed.

Nor operator

The only operator in ((?)?)? is nor. Nor is an universal logical operator, in other words, you can simulate any other logical gate by using just it:

Normal Using just nor
not a false nor a
a or b false nor (a nor b)
a and b (a nor false) nor (b nor false)
a xor b ((a nor false) nor (b nor false)) nor (a nor b)



Symbol Name Function
? nor Creates two new groups (one for its left and one for its right), executes them and sets the outer bit to the result of "noring" the group bits.
( start group Creates a group.
) end group Deletes the current group and stores its bit in the outer bit.
! toggle (Deprecated) If the bit is 1, it changes it 0 and vice versa.
:<name> set name Sets the variable name to the current bit value. The name can only contain one character.
;<name> get name Sets the current bit to the variable name value.
@ push Pushes the current bit value into the stack.
# pop Pops the top value of the stack and sets the current bit to it.
_ has elements Sets the current bit to 1 if the stack has elements, 0 otherwise.
[ start while Goes to the next ].
] end while If the bit is 1, returns the character after the previous [.
= out num Assumes the stack is a binary number and prints it in the decimal system.
~ out char Assumes the stack is an ASCII code in binary and prints its corresponding character.
- out bit Prints the current bit.
$ input num Gets a number from user input, translates it to binary and pushes its bits into the stack.
% input char Gets a character from user input, gets its ASCII code in binary and pushes its bits into the stack.
& input bit Gets a bit (t/f, y/n, 1/0) from the user and sets the current bit to it.
/ break Prints a newline.
