Best way to fill an array of Struct of Float_vs with an array of Struct of floats in VC

[Jaroslav Malec]

Matthias,

As far as I know, in the current implementation you can use *scatter* and
*gather* for these operations.
Please correct me If this is a misconception.

If I'm on the right track on this, could you provide some code examples
that relate
to what Krishna has in mind? It could be contained in the documentation
also.
We would both appreciate it.

Thanks.
