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?
