Your problem is not related to J, and that your example only
display data below 127{a. so that it is not related to utf-8 either.
Since J does not have special handling for non-displayable character,
how to display them is controlled by os (or java for java-frontend).
You can do some pre-processing, eg. there is a pdfesc in plot package
pdfesc_jzplot_"1[ _16]\a.

Ok, this is what I have:
ic=: 3!:4
endian=. a. i. {. 1 ic 1
(endian,0 0 0) { a.
(endian,1 0 0) { a.
(endian,2 0 0) { a.
(endian,3 0 0) { a.
I would like to see these binary forms explicitly in the J Session Manager.
I remember seeing them as such (some strange symbols but distinguishable).
I used J602 earlier. And am using J602 now. So, I my first guess was that
something is different in the windows gui controls on this laptop of mine.
I use this in the following ways:
RESPONSE=: (endian,3 0 0) { a.
a =. cmdr__o 'Mcmdcount__theObj' NB. this is a command send over a socket
and receives the data with a header that describes the data
I can then splice the message as follows:
splice a
+----+-+------+++
| |6|582396|||
+----+-+------+++
and compare the header as so
RESPONSE -: (> 0 { splice a)
1
Does this make my problem clear : I would like to see the various binary
forms distinguished in the J Session Manager. I am using Courier New font.
Is there any (OS) system setting that can help me here?

It is not clear to me exactly what the problem is. What version of J was
your previous system? What is your binary data? Anyway, the following
may help - if not, please give us more details of what you want to do.
The J6 session assumes that literal text (3!:0 is 2) is in utf8 format.
If the text to be displayed is correct utf8, you should see the
characters properly, as long as the font used supports each character.
If the text is not correct utf8, you will see boxes (or other garbage
characters). Note, earlier versions of J did not support utf8. Also, the
point is "not utf8" rather than "not ascii".
The script 'system\extras\config\colorsmp.ijs' is in utf8 format, and
should be displayed correctly by the J6 session, and by any editor that
can detect and display utf8. For some editors, you may need to
explicitly set utf8 as the encoding.
In general, binary data is not in utf8 format, and so will display as
garbage. As Oleg suggests, you can use the hexdump facility to display
binary data, with characters shown only where possible.

1) Did you try opening j602\system\extras\config\colorsmp.ijs with
notepad
and wordpad? Do you see the difference in the rendering of Line No 16? Is
this because notepad is unable to recognize unicode?
2) Unfortunately, I donot have access to my old machine anymore. So, what
I
writing is from what I remember as having seen. All that you have said
below
works as you described in my new machine.
Ok, when I pass messages over the socket, I use binary translation for
the
size of the message. In my previous machine, I was able to see some
representation of the data and was able to spot errors. Now, with these
nice
small rectangles, I am clueless. Of course, I can always pretty print by
decoding. I was just hoping that there was a simpler way....
