Thanks,

but i tried that. The problem is that the result of -capture keep v1 v2 v3 - is that the command is disregarded. As an example; I want to keep v1, and v2, but not v4 for data sets where v1, v2 and v4 are present (and run the same command for all other data sets I have, see below)

Hi Statalisters,

Is there a way to let the keep command do the following?
I want to keep, let's say, three variables v1 v2 v3 before saving data,
but all these three variables do not exist in all data sets for which I
want to run the command (I want to do this with a loop using many data
sets and I use global to define the variables).

I could drop variables instead using "capture drop v4" etc, but that
would become a very long do file.

Cheers

Erik
