Structure padding is allowed in ANSI C, and the way it is done is implementation-dependent. Attempting to use a structure to represent data like this is inherently implementation-dependent. You should be manipulating one member at a time. -- Erik Max Francis &tSftDotIotE && http://www.alcyone.com/max && max AT alcyone DOT com San Jose, California, U.S.A. && 37 20 07 N 121 53 38 W && the 4th R is respect H.3`S,3,P,3$S,#$Q,C`Q,3,P,3$S,#$Q,3`Q,3,P,C$Q,#(Q.#`-"C`- && 1love && folasade Omnia quia sunt, lumina sunt. && Dominion, GIGO, GOOGOL, Omega, Psi, Strategem "Out from his breast/his soul went to seek/the doom of the just." -- _Beowulf_
