Wow, that's really fast,

  octave:7> tic, for CNT = 1:10000, strrep ("This is a % test string", ...
  > "%", "AAAA"); end, toc
    Elapsed time is 9.649048 seconds.
  octave:8> tic, for CNT = 1:10000, _strrep_ ("This is a % test string", ...
  > "%", "AAAA"); end, toc
    Elapsed time is 1.654892 seconds.

Thanks Paul, at the moment I need to do a lot of fast string replacements.
Bye, Thomas

function t = _strrep_ (s, x, y)

  if (nargin != 3), print_usage (); endif

  if (! (ischar (s) && ischar (x) && ischar (y)))
    error ("strrep: all arguments must be strings");
  endif

  t = regexprep (s, x, y);

endfunction
