Thanks, glad you like it!

The menu item for compacting series does not work correctly.
Although the option "last" is specified in the attributes, another
method to compact is used. In contrast, if you use the command
line interface, everything works fine.
Thanks for the report. I see the problem, and it's specific to
running two compaction steps: daily to monthly then monthly to
annual. I've found the source of the problem and fixed it in CVS;
fixed snapshots will follow tomorrow.
If you want to try out yourself, just try to compact these two
files via the menu to a frequency of 1 year. A lot of data gets
lost at the beginning of the series.
One thing to note is that your DAX CSV file is not suitable for
importation to gretl as it stands. You can't include a thousands
separator in such a file. (When I experimented with it I had to open
it in a text editor and delete all instances of '.'.) All the
supposedly numerical values such as "10.666,43" (meaning, I take it,
10 thousand, six hundred and sixty six point four three) are read as
string variables since gretl can't make any numerical sense of such
constructions with two bits of punctuation.
