You can get where you want with two calls to -reshape-, like in the
example below (in which I added a second variable x2).

*-------------------- begin example ------------------------
clear all
input str2 var year USA AUS
x1 1997  0.1   0.1
x1 1998  0.2   0.5
x1 1999  0.1   0.3
x1 2000  0.3   0.3
x2 1997  1     1
x2 1998  2     5
x2 1999  1     3
x2 2000  3     3
end

// this will put the countries underneath one another
rename USA c1
rename AUS c2
reshape long c, i(var year) j(country)
label define country 1 "USA" 2 "Australia"
label value country country
list

// this will put the variables side by side
reshape wide c , i(country year) j(var) string
rename cx1 x1
rename cx2 x2
list
*------------------------ end example ------------------------
(For more on examples I sent to the Statalist see:

Hope this helps,
