Does anyone know about a tool which can detect such situations as the
following:

	procedure xxx (result: out INTEGER) is
        begin
	     if <<condition>> then
	         result := 0;
             end if;
        end;

Obviously, this proc is erroneous and result will not be written if
<<condition>> is FALSE.
However, my Ada-Compiler (DEC-ADA for VMS) does not detect this problem,
because result is written "at least once" in the body of xxx.

Is there any tool which can provide help ???
