Oops, yes this was a bug, now fixed. The reason I jumped to conclusions was because I ran out of stack space once with REBOL on the Amiga and it clearly WASN'T a bug (the same program ran on NT without error). As I said, on the Amiga it was easy to increase the stack size and the program ran fine. - Michael Jelinek -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 16, 2000 4:42 PM To: [EMAIL PROTECTED] Subject: [REBOL] stack space Re: out of stack space usually means an infinite loop with recursion. so increasing it to any amount, no matter how huge, is futile. fix the bug instead.
