Hello Gosi;
3((}.i.)>:)7 NB. It just needs another fork.

Hello R.E..;
Given that the comparison machinery of Less(-.) is not really needed, I
submit the following::
3(}.i.)7
3 4 5 6
Unfortunately it presents the same space usage problems:
1000003 (}.i.)1000007 NB. makes two BIG lists and discards most of them.

Most elegant is

Or if you want to include y
3 (-.~&i. >:) 7

Onderwerp: [Jprogramming] Integers from x to y
Some programming languages have built-in commands that give the integers
from x to y. I thought that would be a nice thing to have in J, so I wrote
this:
f =: [+i.@(0&>[EMAIL PROTECTED])~
Is that a reasonable way to go about it?
regards,
Geoff
