Hello,
I have a long list of exported goods and their annual values (y_1999; y_2000; y_2001...). I want to compute the growth rate for each of these products between 1999-2000 called gro2000; between 2000-2001 called gro2001; and so on till 2003-2004. So I need to create 5 variables. I'm trying to write a simple program of the following sort:

program define growth
local i=1999
while (`i'<=2004) {
gen gro`i'+1=(y_`i'+1-y_`i')/y_`i'
local i=`i'+1
}
end
Instead of all the `i'+1, after the while command insert

local j = `i' + 1

and then use `j' instead of `i' + 1
