I'm learning the evaluation rules for tacit expressions, since that is what's commonly posted as solutions. Is there a utility to generate an explicit definition from a tacit definition?
For example, to generate a tacit expression from explicit 13 : '(+/ y) % # y' +/ % # Is there some routine to expand that out? (I've now learned that its a fork). It seems possible that it could expand out to multiple possible variants -- since as I understand, it's a reduced form. I've looked at fndisplay but didn't put too much time into it yet since I wasn't sure that it's what I was looking for. Along those same lines, j6 shows a representation of an expression in boxes which I've found to be helpful to understand how an expression is grouped. I haven't seen that same functionality in j7 or j8. Does it exist? I find myself spending a fair amount of time taking an expression and then looking up its parts in the Vocabulary to understand what its doing. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
