'abc' ts2 'abcbdefbbcbaa' 3 5 2 ________________________________ From: Skip Cave <s...@caveconsulting.com> To: programm...@jsoftware.com Sent: Tuesday, September 13, 2016 7:48 PM Subject: Re: [Jprogramming] Counting characters Bob, Drat! I was hoping I could just take the expression: +/"1'abc'=/'abcbdefbbcbaa' Which works fine, and just turn it into a tacit verb definition without fiddling with it: ts1 =. +/"1'abc'=/] Or better yet: ts1 =. +/"1'abc'=/ Apparently, when I removed the noun argument, the phrase turned into a 'hook'. I have no idea why this happened. Seems like you should be able to get a verb phrase working with an argument, and then remove the noun and add an assignment to make a tacit verb. Apparently it doesn't work that way though.
