If I am correctly interpreting the sentence "Each formatted number is in a box" from [1], then following phrase should not produce a box:
8!:0 i. 0 ++ || ++ That is, there are no formatted numbers, so there should be no boxes. Put another way, the following is inconsistent: # 8!:0 i. 3 3 # 8!:0 i. 2 2 # 8!:0 i. 1 1 # 8!:0 i. 0 1 Put another way, since 8!:0 deals with "each number", I expect it to act as if it were rank 0, even if has unbounded rank. -Dan [1] Specification of 8!: : http://www.jsoftware.com/help/dictionary/dx008.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
