Try Get_Line.

Yup.  Use Get_Line.

  <display info>

  Put_Line ("Hit any key to continue");

  declare
    Line : String (1 .. 20);  
    Last : Natural;
  begin
    Get_Line (Line, Last);
  end;

  <continue with program>

That function only returns only readable characters, and keeps consuming
the line terminator until it finds one.  In this case, this is not the
behavior you want.

I made a post on this topic a week or two ago, with the title "weird
get_line".  You can look it up at DejaNews.

Try ASCII.HT.  Set_Column (Set_Col?) might be better, though.
