While I haven't spent much time on subArrayRecord, the current code looks correct.
no_elements should be set to the maximum element count here.  Code which
actually reads from this field should be calling rset::get_array_info() to find
the actual length (from NORD).

The previous code wouldn't work properly if the array size ever changed with clients connected.

How many elements are are shown by:
