[ferret_users] limits on CSV field and record sizes


Apparently, there is a limitation of 20 fields (per record) in a CSV
file.  Furthermore, the number of records appears to be limited to 1530.

At least, when I load the file in Ferret 6.9 (file/var=...), it first
shows 20480 (for any csv file).  When reading the values, it sets the
number correctly, as long as it is not more than 1530.  If it is more,
it sets the number to 1530 and ignores the rest of the records.

It is normal to use CSV files for observations, because observations
are usually point data, not gridded.  Many observational data sets are
much larger than the above stated limits.

Is it possible to increase these limits in Ferret significantly?
