Thank you Brian, for taking the time to help! You are right that I omitted the left argument, but I was rewarded with that with a domain error. (And I am very impressed that, even with the loss of the formatting hints by the copy/paste/send involved you knew that test was a dyad. The format of the message was much clearer to me before I hit send and the mail/forums reformatted it. And admittedly I didn't know that the function test needed two arguments. I do wish the forums would allow screen captures and other attachments. )
The error occurred after that, when I tried to advance the lab. My only suspicion is that I entered Ctrl-comma vs Ctrl-period, but it wasn't obvious. Notice that the lab continued active after the error. Is that what jhs is expected to do when unexpected control characters are entered? > On Dec 7, 2019, at 2:27 PM, 'Jim Russell' via Beta <[email protected]> wrote: > > comma > On Dec 7, 2019, at 8:08 PM, Brian Schott <[email protected]> wrote: > > It looks to me as if one problem is that you did not supply an x value to > the dyadic verb test in lesson 43. > > --- > (B=) > >> On Dec 7, 2019, at 2:27 PM, 'Jim Russell' via Beta < > ---------------------------------------------------------------------- > For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
