'''MalbolgeFUCK''' is a one-dimensional [[esoteric programming language]] invented in 2026 by Aekvixay Chantavong, designed to be deliberately hostile to programmers.
==Language overview==
'''MalbolgeFUCK''' is an interpreted, self-modifying language built around a one-dimensional memory array and a small set of instructions. Programs are executed inside a virtual machine where code and data share the same memory space.
Instruction decoding is indirect and depends on the program counter, the contents of memory, and a dynamically changing encryption table. As a result, the instruction executed at a given memory location cannot be determined by inspection alone.
The language provides only six instructions. These instructions operate through non-linear arithmetic, base transformations, and rotational operations on unbounded integer values. Simple operations such as subtraction or direct comparison are intentionally absent.
After each instruction is executed, memory is modified by an encryption step that affects the current cell and its neighbors. This encryption evolves on every execution step, causing programs to change as they run.
Due to these properties, MalbolgeFUCK programs require careful anticipation of future machine states. Even trivial tasks may require reasoning several steps ahead in the execution process.
==Virtual machine==
'''MalbolgeFUCK''' programs execute within a virtual machine consisting of a one-dimensional memory array and a small set of registers. Code and data share the same memory space.
The machine provides three registers:
* <code>pc</code>, the program counter, which holds the address of the next instruction to be executed.
* <code>a</code>, an accumulator register used for arithmetic and input/output operations.
* <code>d</code>, a data register used for indirect memory access and control flow.
Memory consists of 65,536 addressable cells indexed from 0 to 65,535. Accesses outside this range return a value of zero. Each memory cell can store an unbounded integer value.
Programs are loaded directly into memory starting at address 0. Any remaining memory cells are initialized to zero.
Output is written to a stream referred to as standard output (stdout). Input is read as Unicode characters and stored as integer values.
Execution proceeds step by step until a stop instruction is encountered.
==Instruction decoding==
In '''MalbolgeFUCK''', instructions are not executed directly from their stored values. Instead, the instruction to be run is derived through a decoding formula that depends on the program counter and memory contents.
For each execution step, the virtual machine computes a value using the following process:
* The current program counter value
* The value stored at the memory cell addressed by the program counter
* A fixed offset and modular reduction
* A reversal of the binary representation

The resulting value is reduced modulo 127 and mapped to one of the language’s instructions.
