Hello All, This where I got my conclusion.
I mentioned before that blocks are a container type. An ordered sequence of values. Actually they are an ordered sequence of un-evaluated values. What that means is that when a block itself is evaluated the values it contains are not evaluated. The values a block contains are evaluated when a function is applied to the block http://www.codeconscious.com/rebol/articles/rebol-concepts.html#Firsttrapforbeginners Is the last statement correct?
