You might try require'general/misc/format format/printf' a=:i.2 2 [ b=:6 'v1: %d\nv2: %s\nv3: %d\n' printf b;(flatten a);b
Note also that if you are re-using a format string many times, you can save some overhead by "pre-compiling" the format string and reusing that result, along these lines: fmt=: cprintf 'v1: %d\nv2: %s\nv3: %d' fmt printf b;(flatten a);b fmt printf 3;(flatten b);4 I hope this helps, -- Raul On Mon, Aug 23, 2021 at 10:24 AM 'Rudolf Sykora' via Programming <[email protected]> wrote: > > > Raul Miller <[email protected]> writes: > > > The problem here is that you told printf that you were giving it a > > list of characters but did not do so. > > Thanks. > > Is then this the right way to print such a combination: > > b=: 6 > a=: i. 2 2 > '%d%s%d' printf b; (,((":a),"1 LF)) ; b > > or can the middle part be made simpler? > > > Ruda > ---------------------------------------------------------------------- > For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
