Re: Character/Integer Conversion

["DuckE" <nospam_steved@pacifier.com>]

My answer is an example:

function CkSum( msg : String ) return integer is
  result : integer := 0;
begin
  for ii in msg'range loop
    result := result + character'pos( msg( ii ) );
  end loop;
end CkSum;

I hope this helps,
