Hi, Can anybody elaborate on #/.~a
I don't understand the presence of ~ in that sequence. Is this another example of a fork/hook?

Hi. I'm still at verb sequences and I have a question which I am guessing that is more of a rank solution. I have the following values: [a=: 1 1 2 2 3 5 5 5 1 1 2 2 3 5 5 5 [b=: 3 4 5 5 3 1 2 3 4 5 5 3 1 2 What I wanted to do was count the number of matching numbers in a that are in b. So potentially, my result should be: 1 0 3 3 1 2 2 Which if I append to the b noun, I should get: 3 1 4 0 5 3 5 3 3 1 1 2 2 2 I can actually solve this by using a for loop but that's what I'm trying to avoid. So I reasoned that I can count by each number like so: #I. a e. 5 3 #I. a e. 4 0 Using verb sequencing, I can recode this as: a [EMAIL PROTECTED]@e. 5 3 a [EMAIL PROTECTED]@e. 4 0 So far so good. Now this is where I hit a snag, I tried to use the code above against b and I get the following: a [EMAIL PROTECTED]@e. each b |length error | a [EMAIL PROTECTED]@e.each b a [EMAIL PROTECTED]@e. ,.b 0 a [EMAIL PROTECTED]@e. every b |length error | a [EMAIL PROTECTED]@e.every b a [EMAIL PROTECTED]@e. "_ b 8 a [EMAIL PROTECTED]@e. "0 b |length error | a [EMAIL PROTECTED]@e."0 b a [EMAIL PROTECTED]@e. "1 b 8 a [EMAIL PROTECTED]@e.@> (< every b) |length error | a [EMAIL PROTECTED]@e.@>(<every b) a [EMAIL PROTECTED]@[EMAIL PROTECTED] (< every b) |syntax error | [EMAIL PROTECTED]@[EMAIL PROTECTED](<every b) So as you can see, I still have a long way to go. :( r/Alex ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
