Grr) An EXECUTABLE is identified by the first four bytes (Ie, first LONG WORD) which happens to look like 'MZ..' in a hex viewer. The MZ is therefor simply an indicator that the file is (most likely) executable, and means absolutely nothing as to what compression (if any) is used. (If It didn't start with an MZ, it wouldn't be EXEcutable, GET IT?????) -- David Le Blanc : Email: david@mlb.geomechanics.csiro.au : "I'll be back before you can say CSIRO Division of Geomechanics, : antidisestablishmentarianism, P.O.
