Perhaps we are not talking about
the same thing here. I was assuming
that -x- and -y- are _variables_.
If this is a problem in producing a single
value -- held in Stata as a macro or
a scalar -- given another macro or
scalar, then the code should be
of this form
if `x' == 0 {
local y = 1
}
else if `x' > 1 & `x' < 10 {
local y = 2
}
else if `x' > 11 & `x' < 20 {
local y = 3
}
else local y = .
