Mike,
Not that I know of. You might be able to build the list as a macro,
using a loop that exploits the structure of the 70 names. But really,
70 isn't so very many -- why not just list them explicitly, like this:

loc mylist gg hh ii		// etc etc
loc mylist = subinstr(" `mylist'"," "," @_",.)		// nb leading spaces
reshape long `mylist', i(id) j(country) string
