[Gretl-users] Re: delete variables
Hello Sven,
Thanks! Of course, it works. And, perhaps, this alternative is bit more
efficient at it requires one step less. I buy any of the two solutions
provided.
Warm regards,
Cruz

Try this
<hansl>
open denmark.gdt -q
list keep = LRM IBO
list drop = dataset - keep
delete drop
</hansl>
Or, since you mentioned "save", maybe it's worth pointing out that the
'store' command also accepts a list of variables. So you could simply do:
store myfile.gdt LRM IBO
(or: store myfile.gdt keep, with the 'keep' list defined as above)
at the end of your work with the data.
cheers
sven
