Pascal, hi Possible use of ~ in this area is not something I was aware of (now has found it under evoke definition of the old vocabulary), thanks. I think "Do" suits me better -- I'm using it as a helper to sort/filter several columns stored in vars at once, not sure evoke will work here, see below (BTW, allVars below is good for me, but I suspect it may be written as a single tacit adverb but digging there hurts my brain too much)
'allVars' man 'x u allVars y: apply u and box results for each var name in string y, ex: 0 1 1 #allVars ''a b'' [ ''a b'' =: i. 2 3 /misc.ijs/' allVars =: 1 : 0 ([:u ".)&.> cut y : (x u ".)&.> cut y ) вс, 27 февр. 2022 г. в 14:09, 'Pascal Jasmin' via Programming < programm...@jsoftware.com>: > there is also > > 'a'~ > > 5 > > name~ > > 5 > > Which is a more direct "indirect" referencing. > > The new AV(V) trains also simplify this approach in a tacit expression > > > > 'a' (~ + ]) > > 5 + ] > > > > On Sunday, February 27, 2022, 05:09:30 a.m. EST, Danil Osipchuk < > danil.osipc...@gmail.com> wrote: > > > > > > Elijah, argh, many thanks - that is it > I had a vague memory there was something but just couldn't come up on my > own > > Danil > > вс, 27 февр. 2022 г. в 13:02, Elijah Stone <elro...@elronnd.net>: > > > Something like this, perhaps? > > > > a=. 5 > > b=. 6 > > name=.
