I just verified nothing has changed in Unix/Darwin from j504
through current j602. But was amused to notice that wc is
different in Red Hat Linux 8.0 3.2-7 and Darwin and Fedora.
Here are the results of wc on a file "a." (which is just j a.)
in those three systems respectively -
[EMAIL PROTECTED] jkt]$ wc a. # Red Hat Linux 8.0 3.2-7
1 1 256 a.
iMg5:~/Desktop jkt$ wc a. # Darwin
1 3 256 a.
[EMAIL PROTECTED] ~]$ wc a. # Red Hat 4.1.2-13 (Fedora)
wc: a.:2: Invalid or incomplete multibyte or wide character
1 1 256 a.
I guess/think the last one is progress towards more alphabets.
Perhaps it is equally "funny" that Red Hat (old and new) don't
"see" the blank in a. to report 2 "words" but also strange that
Darwin reports 3 words... Even adding a linefeed to the end -
echo '' | cat a. - > a.lf
doesn't change the count of words (but does get 2 lines) in each
system:
[EMAIL PROTECTED] jkt]$ wc a.lf # Red Hat Linux 8.0 3.2-7
2 1 257 a.lf
iMg5:~/Desktop jkt$ wc a.lf # Darwin
2 3 257 a.lf
[EMAIL PROTECTED] ~]$ wc a.lf
wc: a.lf:2: Invalid or incomplete multibyte or wide character
2 1 257 a.lf
I think this shows the general attitude of the "computing
community" as regards edge conditions...
I'm happy with the way j stdin/out works in these environments.
(and I realize you only asked Window folk to look at the change... :)

Please take a look and see if the change works as desired.
please take a look and report problems.

Subject: Re: [Jbeta] Stdout write in binary mode for windows
To be specific, concerning what stream numbers to use:
I suggest changing existing 4 for binary output and not
adding new numbers (6 and 7):
- or it will require same added to Unix versions for
consistency
- or will make J and user code more complicated
- there aren't many (if any at all) uses of 1!:2&4 at least
for Windows, and it will be easy to fix
- this will be used for true binary output such as
images or precise text
- 1!:2&4 is unlikely to require CRLF ever and
easy to compensate
So it's easier and CR will never be missed.
There is no need to change stderr (1!:2&5), because it's
always for text output and not binary, so CRLF is OK.
If anybody thinks otherwise, please comment.

Is there anything in j602 related to
binary stdout/stderr?

[Jbeta] Stdout write in binary mode for windows

I will take a look at this. It is a good suggestion and something will
be done unless there are unforseen problems.
Are there compatibility issues with old uses?
What about 5 for stderr.
It might be easier (and take less analysis) to simply add 6 and 7 for
binary versions of 4 and 5.
Joey and other console users: any comments on this?

Now there is no way to emit binary data
using stdout. For example, this is important
for CGI binary output, such as images;
or if J is used as a slave process to return
binary data through the pipe, like task.
Is it possible in the upcoming release to
change the implementation of 1!:2&4
so that it uses binary mode instead of text mode?
If somebody needs to output CRLF in text for windows
it easy to do in J before calling the function
>> or use "echo" (1!:2&2) which could remain in text mode.
