Thanks for the information. Here's a revised request:
I have a file with a variable varA[dimA][*], where the rightmost dimension
is a vlen dimension.
1) How do I read the data? Can/must I make a series of requests: for
varA[0][*], then varA[1][*], ...? Is there an alternative?
2) Is there a way to find out the various sizes of the second dimension
other than looking at the sizes of each of the responses for varA[0][*],
varA[1][*], ...?
3) If a variable uses a vlen dimension, will it always be the rightmost
dimension?
Thank you.
