You seem to have noticed that a function returns only one value
because your last version combined the RETURNs into a list.

LOCAL d:=0; // is allowed since a simple value can be assigned in a variable declaration
but the code is more clear the way you do it.

Note that you didn't declare the FOR lpv
I remember once having code where I needed even FOR variable declaration.

Yep, I noticed that. Since lpv is not declared, it ends being used as global and so returns value when function returns.
