M,
you certainly can use coordinate subscripting. This method is dependent
upon what your coordinates look like. if your coordinates go from -180 to
+180 then you need to use those values while coordinate subscripting. if,
as in your case, they go from 0 to 360 you need to use those values.
for example
y = x({-20:20},{270:360})
in your case you need to mentally convert the region you want into
360-mode and then subscript.
