Ok, that is helpful. I presumed I wouldn't be able to use a large portion of them. It is difficult to know sometimes if I simply made a mistake, or if it is a script I can't use. I employ the syntax and diagnostic help when I don't get a result, but it would be nice if it would inform me of 'forbidden in dd' script attempts. Or something. It also took some time to realize the 'y' coordinate is backward in scripting vs. HUD. Anyway, I am still learning it, but I have had good success and would like to add some of the more complex scripts I've seen around. Though I am discouraged to go big until I have a better idea of what I can do.
