As a subquestion, I am also want to reverse the bytes (but not changing the order of letters in each byte). e.g. beef would become efbe My solution is (which I used some of the answers to my last question to formulate) a=: '93930001029303040593060708' , _2 (|."_)\|. a Implicit: reverse=:,@:( _2 &(|.\))@:|. Any interesting solutions to this? I would be interested in a way that only uses |. once at most. > Date: Fri, 19 Jun 2015 08:33:35 +0200 > From: agroeneveld...@gmail.com > To: programm...@jsoftware.com > Subject: Re: [Jprogramming] Inserting spaces in a string > > Here's one with variable RHA > > '93930001029303040593060708' (;: inv@ (<\~-)) 2 > > > Vijay Lulla schreef op 19-06-15 om 03:32: > > s=.
