Jmp(usize)

Jumps to the specified index.

JmpFalse(usize)

Jumps to the specified index if the value on the stack is false.

SetVar(usize)

Pops the top element off the stack and binds it to the specified number.

GetVar(usize)

Retrieves the variable with the specified index and places it on top of the stack.
