Wow! Thanks to all for the many helpful responses! The power of the J fora is most evident, especially the way it elicits responses based on different perspectives that provoke one to widen one's own perspectives. For me the sticking point was that the :0 construct appeared to 'step around' the argument that precedes the fret (the fret ending the line containing the 0:) that starts the subsequent script terminated by the next isolated right parenthesis. This 'stepping around' did not seem to me to be in the least intuitive. Tracy's first post in this thread was particularly helpful, especially when I expressed it as ( 0 :'foo';3 :'<y' 'X' ) which together with Raul's reference to scripts being 'consumed' by :0 made me reconsider the nature of scripts. Until this point I had thought of a .ijs file as a script, in line with the ideas and terminology presented in the J Primer. However there is a much more precise and specific J definition of 'script' (Dictionary / II. Grammar / H. Frets and Scripts) ...... Once again, thanks to all. Internal Virus Database is out of date.
