Thanks Mike. It is looking good.

I take it that the 'value' parameter for the setter method is a reserved word in
that context and is a Euphoria object datatype. That would mean that the setter
could receive a sequence and deal with as required.

property integer height
public get        
  return this.h
public set
  if sequence(value) then
    value = toInteger(value)
  end if
  if value<0 then
     throw Type_Error("Height must not be negative.")
  else
     this.h=value            
  end if
end property

foo.height = "23"
