Yes, this is exactly what I was looking for--and, as I had anticipated, it's much simpler than I had originally thought. I enjoy learning how things work, and so I immediately went to the Dictionary to figure out how # (copy) could be used this way, since I obviously hadn't caught that on my first times trying to understand the command and how to use it. That's one of the main problems for beginners with the Dictionary examples: they usually demonstrate more advanced uses of the verbs (which I don't object to at all!) but omit the simpler uses that beginners to the language would thrive on--in this case, for example, including the following 4 "simple" uses (among perhaps others) of the # "copy" command could have been helpful for beginners, to give some clues of possible applications of the command: 3 # 0 0 1 2 3 # ,: 0 0 1 2 3 # 0;0;1;2 3 # ,: 0;0;1;2 Ken Iverson's educational materials (most on the Jsoftware site) are just full of the kind of examples I wish were in the J Dictionary. (You can tell he was an educator. Pity he didn't write more!) Maybe what's needed is *another* document: a "J Dictionary of Examples" or, perhaps better yet, a "J Encyclopedia of Examples" (since an encyclopedia has far more information than a dictionary)--where there might be pages and pages of examples for each verb, perhaps some even with nonterse (I hesitate to use the word "verbose" on this list!) explanations. ;-) Thanks for your response--it was very helpful to me!
