Daniel, There is no consideration in the LRM for port versus local variable type resolution. The type selected is the type that is visible at the point that the type reference is seen. In this case, I would expect both "i" and "loc" to have a width of 8 since the visible "TR" at the point of reference is the one inside the function. Gord.
