⌬

⌬ is a language based very much on ☭. It uses only its phase one instructions.

Memory

⌬ uses the registers as memory:

a = 0
w = 0
q = 0
p = 0
g = 89404137

as well as its own program. Note that every register is updated to its absolute value every time its value changes.

Instruction reading

⌬ instructions are read with the formula:

$\left(\left(\left((c\oplus q)+(i{\bmod {3}})+(g\gg 24)\right){\bmod {3}}\right)+3\right){\bmod {3}}$

in which i is the current index of the command pointer, and c is the current command characters byte code. The program halts when the end of the code is reached.

Instructions

Once these have been read, each possible value has an assigned command:

Caption text

Value	Instruction
0	Mutates internal accumulators and shifts keys: a += 3 w += 7 q -= 43 p -= 13 g ^= 0xCAFEBABE
1	Mutates internal accumulators and shifts keys: a -= 2 w -= 5 q += 67 p += 17 g += a ^ w
2	Synthesizes a candidate byte b using the formula: $b=\neg \left(\left((a\lor w)\land h\right)\oplus q\oplus (g\land {\text{0xFF}})\right)$ Then, the character with the same byte code is appended to the program, and the PRNG is penalized (g = 0xDEADBEEF).
