drop if(`x' == .)

For one thing I would not describe this as 'looping over the
observations'. It is not an explicit loop (which is generally to be
avoided).
Ooops, I did of course mean what I wrote in the comment as opposed to
at the start., i.e. loop(ing) over variables.
Apologies for any confusion this may have caused.
