Fred - Your example had the -if- qualifier  !min(b_*)  . What does it
mean?

Thanks

Al F.

Apropos of the recent discussion of inlist, I have often wondered why
Stata doesn't allow varlists in functions, but instead requires comma
separated lists. For example,

missing(,a,b,c,d,...) is required. Why not a varlist? I can't quite see
any difference. However, in terms of programming, a varlist is much
easier.

reg y  a b c if !min(b_*)

is much easier than typing each of the 10 b_ variables which may be long
and easy to misspell.
