If anything, Stata gives you more than you asked for which I do not find alarming. Line 19 in webuse.ado (*! version 1.2.0 04jun2007) simply takes the -using- statement and disregards anything else...

Yes, Clive,

but it is that one case when it should not work like it works. It should [IMHO]

1) abort with an error "varlist not allowed", or
2) load only variable foreign from the dataset, not the whole dataset.

Current beahvior is not consistent with how other commands behave. Not
a big deal though,
but I was surprised today.

Regards, Sergiy

does webuse support variable list? It aborts with an error message
when if or in is specified, but proceeds with a variable list. It
loads the complete dataset and not only those variables specified in
the list (in Stata 9.2/10.1). Is this intended for compatibility with
something?
