This worked--thanks! Now if only 1!:1 1 would work in scripts... > For what is worth, C, similar to J, does not have any i/o instructions in its > core language. All i/o are supposed to be done by external i/o library. I've no problem with including libraries as sources of additional commands. (I consider them as part of the extensibility of the language, and I do includes all the time with most of the J scripts I write.) Which J library contains the basic keyboard input/screen output routines I requested? > You can try the ncurses addons for text mode interface. I was completely unable to find anything in J602 containing "ncurses" within the filename or within the file itself (except a single reference in a file of changes between J601 and J602 referring to Linux/Mac). Then I realized that I hadn't checked in a while for addon updates. Sure enough...there it was! Now to figure out how to use it...
