I get different results for the example listed on the page http://www.jsoftware.com/help/dictionary/samp18.htm
(length=: +/&.:*:) disp=: ] - 1&|."1 sides=: length@disp sides 0 0 4 ,: 3 4 7 1 5 5.65685 NB. The page shows 0.5 3.5 4 Why? Similarly I get different results for semiper and HERON too (obvious because they both use sides). BTW, I'm using J701.
