What is the right way to do this?
I have the series in databank format (the traditional TSP and

I've documented the databank format here:

Is it true that `genr` is deprecated? The command reference uses

Well ok, the command reference is a few years old, but even the

Finally, can I assume `series` is just an alias

User Guide 4.4 refers to the `import` command.
It does not appear in the command ref.
If you go to the console and type::

you are told `import` is not a gretl command.
It is of course, but apparently undocumented?
