Some non-mathematician friends once asked me why 1 isn't a prime. The answer I gave, off the top of my head, is that it makes many statements shorter, else you'd saying lots of times, "for every prime > 1" or "for every prime other than 1". It is now years later, and I have had lots of time to think about it, but I am still tempted to give the same answer. There is also the use of "odd prime" to denote all primes other than 2.
So, the question is, how often do you need to say "all arrays other than atoms"? My guess is, not very often. Less often in J than in APL with the concept of prefix agreement in J. ----- Original Message ----- From: Henry Rich <[EMAIL PROTECTED]> Date: Wednesday, April 4, 2007 4:01 pm Subject: [Jgeneral] Need a word for a non-atomic array > Like Oleg, I had thought that an 'array' had to have > rank > 0.
