OK, I accept that a Stream is not indexable; after a stream is 
created, the position on the underlying file is not available for 
adjustment.

The Streams modules in ETH Oberon and A2O have Close procedures. I'd 
expect Streams.OpenFileReader() and Streams.Close() to be paired.  The 
Mail module opens several streams; there is no Close.
  
Disposal of obsolete streams is left to the garbage collector? If 
there is risk of obsolete streams occupying to much memory, I should 
invoke garbage collection?

Thx,                          ... P.L.
