Hi Linda, a=:1 1 2 3 5r1 2 3 5 8 NB. 5r1 is just 5, so really this is just creates a list, as r is not a verb a 1 1 2 3 5 2 3 5 8 1 1 2 3 5 ([: x: %) 1 2 3 4 8 NB. I would normally write 1 1 2 3 5 x: @: % 1 2 3 4 8 , but I know you prefer [: 1 1r2 2r3 3r4 5r8 NB. ([: x: %) is a verb that works the way you expect
Hope this helps. Cheers, bob > On Apr 6, 2019, at 3:25 AM, Linda Alvord <lindaalvor...@outlook.com> wrote: > > a=:1 1 2 3 5r1 2 3 5 8 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
