1. Amino-acid assembly (.aa)
2. Each letter is an opcode.
3. K (Lysine / LIT) pushes a number. M is multiply. H is halt. Strings emit themselves.

46 opcodes

The instruction set is 46 opcodes, one for each human chromosome. See OPCODES46.md. The original 36 are unchanged. These ten are assembly-only; gene mode still emits the natural amino-acid letters. | Sym | Name | Stack | ............Meaning | |-----|------|---------------|---------------|| |* | JNZ | (flag addr --) | jump if flag != 0 || |@ |ROT | (a b c -- b c a) | rotate top three | | & | NIP | (a b -- b) | drop the second | | = | NE | (a b -- flag) | 1 if a != b | | / | GE | (a b -- flag) | 1 if a >= b | | ^ | LE | (a b -- flag) | 1 if a <= b | | \| | MAX | (a b -- max) | greater of two | | ; | MIN | (a b -- min) | lesser of two | | . | ABS | (a -- \|a\|) | absolute value | | , | DEPTH | (-- n) | push stack depth | Word forms: JNZ ROT NIP NE GE LE MAX MIN ABS DEPTH. A bare - is still DEC; - followed by a digit is still a negative literal.

2. Packed DNA (.dna)compile --dna writes a FASTA file:

ATG + 16-bit length + payload + TAA

3. Gene mode (--gene)A coding sequence is read like a ribosome:Find ATG (START / Methionine). The start codon is skipped.
Each following codon becomes its amino-acid opcode.
After Lysine (AAA / AAG = K / LIT) the next codon is a number 0–63
in base-4 (A=0 C=1 G=2 T=3).
TAA / TAG / TGA become HALT.

Example gene that prints 42:

ATG AAA GGA AAA AAG GCT TAT TAA
     K   40   K    2  ADD PUTN STOP


40 is codon GGA because G=2,G=2,A=0 → 2*16 + 2*4 + 0 = 40.

LanguageComments start with #. Labels are :NAME. Bare names push that address.
Jumps take the address from the stack.Want

T store (val addr --) / F fetch (addr -- val)

JZ stack effect is (flag addr --). It jumps when flag == 0.Put subroutines after a jump to main, or execution will fall into them.
