You can try 15!:14<'name' to get the address and then
pass this address using signature x.
But if you pass address directly, J will not downsize/upsize
the array, your callee should aware of this.

When trying & , I apparently do not know what I am doing, because it
immediately crashes my session.
However, I do feel meanwhile that I get an increasing number of copies of
my (large) dataset in memory, so perhaps I should find out what I should be
doing. As I understand, & can help to avoid cop
"The memory is unaliased." refers to the memory as seen by
the callee of cd. Any changes made by callee won't be written
back to the original memory. That's why the value of names
remained unchanged after cd call. Unless you had taken
the address of name and passed the address to cd.

What Bill is saying is that starting in 807, cd makes an copy of any
argument to cd that might be shared by another noun. So, the value of
'res' is put into a temporary block and passed to the DLL. The
temporary block is put into the boxed result of cd. You need to look in
that boxed result,
j807 must get from result of cd, like this
0 3{ (sqrdll, 'sqr i i *i *i') cd (#y);y;res

Pepe, have you seen the Rosettacode entry for Y-combinator in J ?
