Suppose z is boxed strings, eg z=: ;: 'alpha bravo charlie' I half-recall there's a neater (single-primitive) way to recover the string 'alpha bravo charlie' from z than:
b2o=: [: }. [: ; ' ' ,&.> ] b2o z alpha bravo charlie but I've forgotten what it is and can't seem to find it in Voc or Dic. On the page for "Raze" (;) the Dictionary says archly: The fit conjunction (;!.f) provides fill specified by the atom f but AFAICS (;!.' ')z is the same as ;z , viz: 'alphabravocharlie' . Nor incidentally is (;) listed as such on the page for "Fit" (!.) . I observe however that: ;:inv z alpha bravo charlie But what's in my mind is a way of interleaving some other letter, or 2 spaces, or comma-space, etc. BTW timer (6!:2) tells me that ;:inv is slower than b2o . ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
