I just began to ponder this thread. Do you think E is the same as D?
D=. (n%2) > (?]) n$d
E=. ?(n,d)$2

Next, isn't c1 the same as c11?
I make silly little scripts like this and I run them in a new Jconsole and
then do T '' lots of times until I'm pretty sure they agree.
T=: 3 : 0
n=:1+?6
d=:1+?6
]D=:(n%2) > (?]) n$d
]E=:?(n,d)$2
]c1=:0= ? A=:(2$d)$(>. d%2)
]c11=:?(d,d)$2
F=:($D)-:$E
G=:($c1)-:$c11
Yes, that is the concise explanation. And, as Marshall says, it's
probably better that way. It certainly makes my current project easier
if that is so.

Hi
I would like to use Windows 64bit J602 for handling zip file. The 32bit
version does work well, but the 64bit version fails as follows:
load'~addons/arc/zip/zfiles.ijs'
fexist jpath '~addons/arc/zip/test/test.zip'
1
zdir jpath '~addons/arc/zip/test/test.zip'
|domain error: unzOpen
This looks promising:

But I run into problems when I try to follow its steps:
load 'arc/zip/zfiles'
fexist jpath '~addons/arc/zip/test.zip'
0
fexist jpath '~addons/arc/zip/test/test.zip'
1
zdir jpath '~addons/arc/zip/test/test.zip'

When n=7, d=3, D will contain only 1s while E will typically contain a
mix of 1s and 0s.
I do not know enough about the purpose of this code to comment on
which is better.

Actually, this is a bug in the original code. Thanks Linda! It should be:
(d%2) > (?]) n$d
The idea being that each row (domain) has half of it's possible values
set. Which is different from what you suggest because you may get a row of
all zeros which is already inconsistent and so there is
Hi Linda, you are a bug finding machine! c11 is simpler than the original
and is more correct than the latest version I put up on pastebin. I
introduced a bug by removing the 0= from this although I shouldn't have.
Cheers,
