This method links stream object to an existing file:

Method imagefile()
{
  set obj = ##class(Sam.binary).%New()
  read "enter path to image: ",img
  set st = obj.Image.LinkToFile(img)
  write $System.Status.GetErrorText(st)
  set st = obj.%Save()
}

1. Notice what Eduard wrote:

set st = obj.Image.LinkToFile(img)

2. Your class is:

Class Quadramed.Chennai Extends %Persistent

and in your imageFile method you have:

s obj = ##class(Sam.binary).%New()

maybe this is your problem?
