I guess I still have some thoughts and comments about the function signature and defaults and what kind of text file input arrangement is supported in detail, but I don't have time right now. Since it's pure hansl I'm happy to make concrete code proposals later.

Fine. I now have an improved prototype which I'm happy to supply on request. It now has some proper error-checking, and it adds "unit" and "time" series to the CSV file to make it easier to get gretl to recognize the data as a panel.

OK, great. On and after Thursday or Friday I should have some time for this. If you're not working on it until then, you might as well send it now.

Alright. Hansl and toy test file attached.

Hmm, actually from the explanation in the guide I had a different kind of input file in mind, namely something like the following (also attached as a standalone file):
x1
1965 1970 1975 1980 1985
AR 100.0 110.5 118.7 131.2 160.4
AZ 100.0 104.3 113.8 120.9 140.6

x2
1965 1970 1975 1980 1985
AR 103.0 112.5 111.7 136.2 168.4
AZ 109.0 100.3 110.8 128.9 141.6

Your function fails on this kind of file. I have started some string-processing work to handle this, but I'm having doubts -- what are we really targeting? It would be helpful to have a real-world example.

thanks,
