Thanks. That took care of my problem. I will keep a sharper eye for such
things in the future.

I confirm the same behaviour
with the auto data, substituting -mpg- for
-comprate- and -weight- for -week- and
-foreign- for -unit-.
I fixed all problems by removing spaces between -by- and
-(<its argument>)-.
In essence, no space is ever _required_ there
and I don't believe that one is ever used in
code examples in Stata documentation. Although
your examples seem inconsistent, it seems that
Stata is trying to read your mind from what
you typed, and succeeding sometimes and not
others. Sometimes spaces are ignored as superfluous, but
not always.
Stata isn't human but as in other contexts
you can be misunderstood if you bend linguistic
rules too much. I recommend always following
an option name immediately by any argument in
parentheses that it may have.
