The easiest is
... if inlist(x, 0, 6, 7, 9, 500)
You say "not" in some cases but not others.
... if !inlist(x, 0, 6, 7, 9, 500)
negates that condition. (It's going to
select any missings on x.)
It's worth a scan of the on-line help
on functions to see which would be useful
in your work.
In related territory there are at least
