Exactly. 'tco' does not make much difference in total running time. It is all about stack usage. Try with a limited stack size: : (stack 8 8) # Stack sizes 8 KiB -> 8 : (co 'a (yield)) # Start a coroutine to segment the stack -> NIL : (fiboTco 99) -> 218922995834555169026 : (fiboRecur 99) !? ((N A B) (if (=0 N) A (recurse (dec N) B (+ A B)))) T -- Stack overflow ? Give up: No stack ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
