Dmitry, Jerry has obviously seen this behaviour under _some_ circumstances,
so perhaps we should think about what those circumstances might have
been!

If the 'Put("Hello");' is the last output before the output file is
closed, probably by ending the program, then ARM A.10.2(3) applies:

   For the procedure Close: If the file has the current mode Out_File or
   Append_File, *has the effect of calling New_Page*, unless the current
   page is already terminated; then outputs a file terminator.

and ARM A.10.5(16) for New_Page:

   Operates on a file of mode Out_File or Append_File. *Outputs a line*
   *terminator if the current line is not terminated*, or if the current
   page is empty (that is, if the current column and line numbers are
   both equal to one). Then outputs a page terminator, which terminates
   the current page. Adds one to the current page number and sets the
   current column and line numbers to one.

Use Ada.Stream_IO, as already suggested, or GNAT.IO - of course the
latter isn't standardised nd its behaviour might change.
