Correct. And also in pil64 and pil21. All other arithmetic operations except add/sub cannot share structures, because the whole number is modified. What *is* used whenever possitle are destructive operations to avoid unnecessary copies. ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
