I am glad it wasn't a -separate- problem. 

The command -separate- itself has never been abbreviatable. When it was
being written one small issue was whether the intended name leant itself
to minor spelling mistakes. ("separate" was one of those words I had to
check repeatedly in a dictionary.) The decision was that if the user
typed -sep_e_rate-, this is promptly corrected with a little message and
diversion of the command to -separate-, as some users may have
discovered. (That is, there is an undocumented -sep_e_rate- command.) (I
add the _ _ only to stop this mailer continually correcting the
misspelling.) This may still be the only instance in which Stata will
accept, and correct, incorrect spelling. An odd side-effect of this
episode is that my long-continued difficulties over the word have

Sorry about the needless anxiety - As Martin suggested, I did have an
old -sep-program lying around that dropped _all. Thanks, Martin

If that is true, it is pretty serious. So I get "unrecognized command:
with my 10.1 Stata. Your error "invalid syntax" makes me think you have
a command that I do not have. What does -which sep- tell you?
