procedure Assign(Source: TPersistent)

 You can assign a TDBISAMTable or TDBISAMQuery stream directly to a TDBISAMParam object using this method. This is equivalent to using the TDBISAMTable or TDBISAMQuery SaveToStream method and then the TDBISAMParam LoadFromStream method. Likewise, you can use the TDBISAMTable or TDBISAMQuery component's Assign method to directly load a stream from a TDBISAMParam object. This is equivalent to using the TDBISAMParam SaveToStream method and then the TDBISAMTable or TDBISAMQuery LoadFromStream method.
