Just noticed that a change for setmode binary was made to the code some time
ago and should have effect in the 602 beta. Haven't looked at the details of
the change but it was the result of the discussions back when this issue was
first raised.
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.

the c or d beta.
