                                 STREAM OBJECT DEFINITION

   A Stream object is something which accepts a stream of text.

   The creation methods will vary on the type of Stream Object, but
   the methods used to write to it and close it are common.

   These are the common methods of all streams.  They should be

   The put_block method was write, but this upset systems whiuch had
   macros for write().
