Fred Wolfe doesn't like this error message
produced by -clonevar- (a command added
to official Stata on 5 October 2004)
when he is trying to assign to an existing
variable.
In effect, Fred is being reminded that
-clonevar- is for producing new variables,
and he is expected to infer that the problem
in his case is that he is not using
a new variable name.
As Richard Williams surmised,
a more direct error message is easy to
produce. I've cloned -clonevar- to that
effect and we'll see if StataCorp like my
genetic engineering.
