compressed strings

I can't seem to figure out the compression.

Never mind, I looked at what HDFview does & figured out that my problem
was using H5S_SCALAR instead of H5S_SIMPLE (that caused the error when
combined w/ chunking), and I forgot to call H5Pset_deflate to set
compression.

Hi Jason,

  I'm glad you've figured this out, but an extra word: unfortunately, setting a compression filter for chunked datasets only affects "direct" data (like integers, fixed-length string, compound datatypes, etc.), not "indirect" data (like variable-length strings & sequences) currently, so you might not see any actual size decrease in your file from this configuration.
