+ This example illustrates the concept of virtual dataset.
The program creates three 1-dim source datasets and writes
- data to them. Then it creates 2-dim virtual dataset and
+ data to them. Then it creates a 2-dim virtual dataset and
maps the first three rows of the virtual dataset to the data
in the source datasets. Elements of a row are mapped to all
elements of the corresponding source dataset.
