To clarify this a bit.
It is possible to download all addons to the Android.
GTK is not running on the Android - at least not now.
Many of the Addons are GTK specific and no need to download them and it
might cause confusion.
Then on the Android you do have two Guis and one is native Android an

To clarify further, my researches suggest that GTK is never going to make
it to the android.
Having said that, Bill Lam is doing some remarkable pre-alpha work
implementing a scriptable gui layer for the android. This api goes as far
as to expose the whole android interface to scripting. This open

In retrospect, I probably should not have used #. and instead done
something like this:
select. *nc;:'u v'
case. 0 0 do. assert. 0 NB. invalid
case. 0 1 do. m v y NB. left bond
case. 1 0 do. y u n NB. right bond
case. 1 1 do. ([: u v)"v y NB. compose monad
Or perhaps I should

Does anyone know if there is any way to link the table of contents in a
.pdf generated by the publish package in J to corresponding pages within
the document?

In a post under "stitching matrices" I used trace poorly to distinguish
the hook - % from the fork [ - %@] (these always produce the same
results given the same data). Here is what I should have done
load '~addons/general/misc/trace.ijs'
f
- %
g
[ - %@]
f 4
3.75
g 4
3.75

AFAIK, there is linking only from the section index, shown on the left. The
package would have to be extended to support linking from the TOC.

Hi
I finally succeeded in starting J602 in MacOSX 10.8 by attaching several
lines in jwd32 shell script except plot function.

Not sure why IFWIN has not been defined in your case. It should be
0 for non-windows platforms.
please try update base library and restart J.

Hi
Thanks a lot. It is a very good comment.
Updating the base library and restart J resulted in success.
