Commands

Against all rules and regulations, I'm using man-style formatting:

• Bold: Type exactly as shown
• Italic: Replace with appropriate argument.

Command	Usage	Equivalent (C)
Manipulation
COPY SRC DEST	Copy the value from SRC [RI] to DEST [R]	DEST = SRC;
ADDI A B DEST	Take the sum of A [RI] and B [RI], and place it in DEST [R]	DEST = A + B;
SUBI A B DEST	Take the difference of A [RI] and B [RI], and place it in DEST [R]	DEST = A - B;
MULI A B DEST	Take the product of A [RI] and B [RI], and place it in DEST [R]	DEST = A * B;
DIVI A B DEST	Take the ratio of A [RI] and B [RI], and place it in DEST [R]	DEST = A / B;
MODI A B DEST	Take the mod of A [RI] and B [RI], and place it in DEST [R]	DEST = A % B;
SWIZ A B DEST	Swizzle A [RI] and B [RI], and place it in DEST [R]
Branching
MARK LABEL	Mark the line with LABEL [L].	LABEL:
JUMP LABEL	Unconditionally jump to LABEL.	goto LABEL;
TJMP LABEL	If the T register is truthy, jump to LABEL. Otherwise, noop.	if(T){goto LABEL;}
FJMP LABEL	If the T register is falsy, jump to LABEL. Otherwise, noop.	if(!T){goto LABEL;}
Testing
TEST A = B	Test if A [RI] and B [RI] are equal. Set the T register to 1 or 0 based on the result.	T=(A==B?1:0);
TEST A > B	Test if A [RI] is greater than B [RI]. Set the T register to 1 or 0 based on the result.	T=(A>B?1:0);
TEST A < B	Test if A [RI] is less than B [RI]. Set the T register to 1 or 0 based on the result.	T=(A<B?1:0);
Lifecycle
REPL LABEL	Create a copy of this EXA and jump to LABEL [L] in the copy.	if(fork()==0){goto LABEL;}
HALT	Terminate this EXA.	exit(0);
KILL	Kill a random EXA.
Communication
MODE	Toggle the M register between local and global mode.
VOID M	Read and discard a value from the M register.
TEST MRD	If the M register is readable without blocking, set the T register to 1, else 0.
