It seems that "without success" is a new variant on that
old Statalist standby "doesn't work"! You don't say
what you mean by it.
These are all legal commands if the data have
been sorted previously by -countrynumber-.
But the first says: within categories of
-countrynumber-, -gen new_var- with
values of 0. You might as well have said
gen new_var == 0
as the -by:- prefix makes no difference
to the result.
The same comment applies to the second.
Please specify a numerical example showing
what you want.
