Henry, I think I get it now. Thanks very much for that long detailed explanation of parsing vs execution. It helped a lot. Also, the examples you gave earlier of dissecting #@> 'a';1 2 and #@:> 'a';1 2 really helped. (Eventually I changed 1 2 to 20 30 so that the 1 and 2 did not get confused with the ranks 1 and 2.) Although I must admit that it was mostly in their contrast that I understood the dissects, not separately. I am still having trouble with all of the richness of information in dissects. It's not a problem with dissect, it's me.
