Howdy John!

Yes, you have it right. You don't have to use the same dimensions for every
variable.

When doing a get of the variable, it is up to you to use the right start and
count arrays, and to have enough space allocated to hold the data you are
asking for.

Does this answer your questions?

Thanks!
