I just thought of this little "idiom" for picking a single item from a
vector, that doesn't require that you write your own block.
It takes advantage of "busports" (as a notational convenience).
Hi,
Another option for extracting one or a range of items from a vector is
to use Vector to Stream followed by Keep 1 in N or Keep M in N. See near
the bottom of this flowgraph for an example:

Best,
