I think the following example shows that in some cases recursion is undesirable. Jerry >> testnr 10000000 == 50000005000000 >> testr 10000 0.0 ** Internal Error: Stack overflow. ** Where: either n > 0 [testr n - 1 x + n] >> testr 1000 0.0 == 500500 testnr: func [n] [ x: 0.0 for i 1 n 1 [x: x + i] x ] testr: func [n x] [ either n > 0 [testr n - 1 x + n] [return x] ]
