Hi all !
I was trying to understand how thecopula verbs =..and=:: works in tacit
expressions.
(p , 0 $ 'p' =.. ]) 'erling'
|value error: p
| (p,0$'p'=..])'erling'
('p' =.. ]) 'erling'
erling
(p , 0 $ 'p' =.. ]) 'erling'
erling
(p , 0 $ 'p' =.. ]) 'fredrik'
erling
(p , 0 $ 'p' =.. ]) 'fredrik'
fredrik
(p , 0 $ 'p' =.. ])
'fredrik' , 0 $ 'p' =.. ]
I wonder if it is really useful in tacit expressions, and in that case,
how it can be used.
It is only used to set variables outside of the expressions, not to use
the variables in the expressions?
Useful in for example debugging?
This is from the documentation:
"The copula verbs =..and=:: are similar to their corresponding copulas
but are syntactically dyadic verbs and may be embedded in tacit
expressions."
Cheers,

Thanks, BIll
I probably knew that route sometime in the past.
Just in case someone else needs to know, this is what I've actually
done. This is for Windows 10, as I said earlier:-
- "create shortcut" from each of the "shortcuts" seen in the Windows
"desktop" (as installed for jqt and jconsole)
- rename each according to taste
- edit the "target" shown in their "properties" dialogue,
according to your suggestion, but with full pathname for
"jx.dll",
in my case: C:\d\j806\bin\jqt.exe -lib C:\d\j806\bin\jx.dll
Pace Thomas Costigliola, I had tried duplicating the whole
installation,
but that's rather greedy for space!
Thanks to both,
Mike
PS - should debug work under JQt with jx.dll ?
CTRL-K invokes a domain error for me:
|domain error: script
| FRINGEBORDER=: (<0 0 0 1)"0 FRINGECOLOR
|[-4849] c:\d\j806\addons\debug\dissect\dissect.ijs
clicking instead on Run/Debug results in
|value error: jdebug_run
| jdebug_run 0

Rename the jx j.dll as jx.dll, then type
jconsole -lib jx.dll
jqt -lib jx.dll
Or rename the official j.dll depending which one will become your
favorite.

OK - I've got the Jx 1.1 j.dll and the various accessory
information, but
suppose I want
to try jx and compare it with the "orthodox" J806?
Do you advocate setting up a complete "JX" installation parallel
with J806
(or J805 ...),
or can it somehow share those orthodox folder/s, given that j.dll
is the
only difference?
Thanks,
Mike

Jx 1.1 Release
A Jx v1.1 Extensions Guide, a J/Jx Cheatsheet, a Jx Assertions script
together with links to a Windows 64 bit dll, a Unix 64 bit so
binaries
(without avx support) and the patch corresponding to the J806 source
(beta-6) can be found at the link [0].

This release introduces a modified primitive (") and, in theory,
for the
first time an incompatibility vs the official J counterpart (J806
beta-6)
;
however, in practice, it is highly unlikely to break any existent
code and
doubters have an opportunity to test their code.
This is a simple 1-decade-old example [1],

See also the threads [2, 3] for recent discussions.
The rank of the verb ?: has been changed to 0 0 0 to make it
easier to
use.
Three venerable facilities are released:
- The conjunction (&:.), for the motivation, see the post [4] (see
also
the
post [5] both, its reference and the embedded discussion for
similar more
recent ideas).
- 102!:0/1 In-place Amend/Append, be very careful (see [6]); if
you do not
know what to expect, play with their corresponding models instead.
PS. There are a couple of other goodies which will be documented
later.
