Does the original 32-bit J6 script work for all cases including
even/odd rank, box and extended? If not, please report the bug
with a simple example. Thanks.

Oh, you are correct, I had forgotten about that.
Thank you.
I wish I could go back and edit my prior email to correct my error.
Restated: on 32 bit J, when the rank of the array is even an extra 4
bytes of padding are added before the data.
Thanks again,

I do not think that you can find any examples of this.
The underlying mechanism only makes sense when mixing structure
elements which have different sizes.
Still, if you can find any examples, it would be great to hear about them.

It ought to be 2*28 (or 56) for J64.
Note that this will change, though, based on the rank of the array.

You need to a Jinit call first to get a handle to a j instance.

J dll call definitely works both 32 and 64-bits. I guess if you
have gained enough experience with 32-bit J call then it will be
trivial to do the same for 64-bit J.
