 i thought of an unbounded string but the program will not go through
the compiler, no matter which one i use or how i change the program.


with Text_io; use Text_io;
procedure main is 
---pre: text is in the mark up language
---post: text has been converted to english
---test: once thru

procedure Get_line is
---pre:text needs to be input
---post:text has been input
---test: once thru
 Line_Buffer : String(Unbounded_String);
  Line_Length : Natural range 0 .. Line_Buffer'Last;
  Line_Store  : array (1 .. 10_000) of Unbounded_String;
  Line_Count  : Natural range 0 .. Line_Store'Last;
begin
  loop
    Get_Line (Line_Buffer, Line_Length);
    Line_Count := Line_Count + 1;
    Line_Store (Line_Count) :=
      To_Unbounded_String (Line_Buffer (1 .. Line_Length));
    new_line;
  end loop;
end;
   
Procedure doubleslash is 
---pre:mark up language has been input
---post:doubleslash has been converted to single slash
---test: /,//,///
begin
 Loop
  For i in s'range loop
    if s(i)="//" then
      s:='/';
    end if;
 end loop;
end;

procedure unformatted is 
---pre: mark up language has been input
---post:/N tag has left the text formatted as it was
---test: /N, /N/N,/N/U 
 Loop 
  For i in s'range loop
    if s(i)=/N then 
       do nothing 
      elseif exit
      end if;         
    end if;      
  end_loop;
End;  

Begin --of main
     s:string;
Put("Please enter text: ");
Get_Line(s);
doubleslash;
unformatted;
end;
