Every explicit verb has an implicit first line: y=. right argument. Every dyadic explicit verb has an implicit second line: x=. left argument

The explicitly provided lines would follow the above implicit lines. -- Raul On Mon, Jan 2, 2012 at 11:18 AM, Linda Alvord <lindaalv...@verizon.net> wrote: > Now I have a new problem: > > why=: 13 :'x + 10*y'/|. 1 2 3 4 5 > erase names 'x' > 1 > why > 12345 > x > |value error: x > > What is x in why ? > > -----Original Message----- > From: programming-boun...@jsoftware.com > [mailto:programming-boun...@jsoftware.com] On Behalf Of Aai > Sent: Monday, January 02, 2012 5:42 AM > To: Programming forum > Subject: Re: [Jprogramming] Binary representation without #: or #. > > > > On 02-01-12 11:21, Linda Alvord wrote: >> This was a while ago, but how about a simple J version: >> >> brila=: 13 :'([:(++:)/|.)"1 y' >> brila >> ([: (+ +:)/ |.)"1 >> n=:5 3$ 0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 >> n >> 0 0 0 >> 0 0 1 >> 0 1 0 >> 0 1 1 >> 1 0 0 >> brila n >> 0 1 2 3 4 >> >> I'm still puzzled by how it works: > #. 1 0 1 0 1 0 1 > 85 > > 13 :'x + 2*y'/ |. 1 0 1 0 1 0 1 > 85 > > or > > 13 :'x + +: y'/ |. 1 0 1 0 1 0 1 > 85 > > > Simple J(?) > > 13 :'x + +: y' > [ + [: +: ] > > or concise: > > (++:) > > Base 10 example: > > 13 :'x + 10*y'/ |. 1 2 3 4 5 > 12345 > > (+10&*)/ |. 1 2 3 4 5 > 12345 > > > -- > Met vriendelijke groet, > @@i = Arie Groeneveld > > ---------------------------------------------------------------------- > For information about J forums see http://www.jsoftware.com/forums.htm > > ---------------------------------------------------------------------- > For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
