You can't access the refcount of a J noun through the J API and I doubt that
we would want to provide such a facility. I think the workarounds for this
lack are simple and that the potential problems and complexity introduced by
having it are not worthwhile.
You seem to be interested in a very tight coupling and so far this has not
been our orientation.
The ultimate and complete solution to this line of thinking and design is
to have the J source. This allows complete integration at the most intimate
level. We have clients who work at this level but it seems unnecessary for
most applications.

sometimes %s is not assignable.
The key thing that is missing in J601 is the ability of J to call a C
function through the C function memory address.
yes, using the existing mechanism is cumbersome.
and the additionaly facility has already been promised for the 602
release.
sorry, i couldn't find this in the forums.
is there a 602 page on the wiki or elsewhere?
also, what about noun/memory management?
can C code access the refcount of a noun?
