Thanks! But it doesn’t appear to generalise to applying successive verbs in the gerund to successive >>items<< in y.
(I checked the dictionary re /. and it talks of “collections” of y. Not sure what that means) For example if y is i.3 5 then I’d like the first verb in the gerund to apply to the first item of y, the second verb to the second item, and so on. Is there a simple solution for this? > On 3 May 2019, at 12:35 pm, 'Rob Hodgkinson' via Programming > <[email protected]> wrote: > > Hi Piet, not ignorant at all ! > > Try using oblique (an obscure feature is that the u in u/. can be a gerund, > in which case it is evoked cell wise); > > g=. *: ` -: `^ > y=. 3 1 0 > g /. y > 9 > 0.5 > 1 > > Found in Section 15 of https://www.jsoftware.com/books/pdf/brief.pdf > <https://www.jsoftware.com/books/pdf/brief.pdf>. > > HTH, Regards Rob > >> On 3 May 2019, at 10:59 am, pietdion <[email protected]> wrote: >> >> Hopefully not an ignorant question. >> >> Am looking for a simple (tacit, non complicated) construction (verb? >> adverb? conjunction?) “c" that takes a gerund and applies the successive >> verbs in the gerund to successive items. >> >> A simple example is >> >> g=. *: ` -: `^ >> y=. 3 1 0 >> g c y >> 9 0.5 1 >> >> What “c” achieves this for arbitrary gerunds g's and y’s? >> >> I realise this can be done in a variety of explicit ways and with the >> agenda construct.
