I'm looking for examples of the use of this rare form: the distributive -so (= Sanskrit -Åas). The one example I have is from Vin ii.139 "... buddhavacanaá¹ chandaso Äropetabbaá¹." Where K.R. Norman thinks chandaso is not a genitive of chandas, but this form of distributive: 'according to desire'; J Brough suggests 'according to the meters'.
Duroielle (p.127) gives atthaso - "according to the sense".
Other examples of this kind of use would be useful.
