Yeah, there is really no virus scanner for ado-files; might be a neat business model, though. Inadvertently -drop-ping all data is just about the worst thing that can happen in Stata short of an outright crash...

Martin - Yes, it was gross ignorance. That program was written in 1996,
when I didn't know much about programming with a -clear- option. Back
then, I didn't know the difference betwewen a ".do" and an ".ado" file,
so I made everything an "ado" file, which then put it into my ado path
without my realizing it.  I shudder to think how many others like this
are lurking in those old files!

No intrusion into Alan`s work practices intended, but I have a hard time
imagining that you would have a -prog- on your ado-path that -drops
_all- without at least the -, clear- option being present...

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
disappeared.

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:
sep"
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?

Feiveson, Alan H.

Hello - More than once I have inadvertently typed something like "sep

var, by(cat)", when I meant to type "separate var,by(cat)" . The
result is an error, but far worse, Stata wipes out my whole data set
when I do this, or even if I simply type "sep":
