-E:1EBD - 7E:1ECC    Pointer to current PLM-like instruction. If positive, store in delay and put 1E8D,X into X. If the argument is also positive, put it into 7E:C000,X and INC X and Y twice. Repeat until the next argument is negative, put a value onto the stack to loop at RTS, and JMP to the argument. Similar to the normal instruction loop, except Y is not incremented, and points to 2 bytes *before* the current instruction, not just after it.
