Instead of "[0]", use "that". Here's why: [n] really means, "give me a sub-stack starting at point n". So [0] is basically saying, "give me the whole valuestack".
"that" means "give me the top of the stack" (the reason it is "that" instead of "this" is because "this" was a reserved word in Ognl). And, just to be super duper tricky, let's play some trivia: Q. What does "[1].that" return? A. It returns the item that is second from the top of the stack -Pat -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robert Douglass Sent: Thursday, October 16, 2003 12:57 PM To: [EMAIL PROTECTED] Subject: RE: [OS-webwork] Understanding Iterators I can ask the same question again with a code example that is perhaps a little easier to understand quickly.
