I agree this is quite an uncommon need. I use it when I have to deal with endianness and I/O. So I mainly use it when dumping content and variables f= rom the memory to files on the disk in a constant endianness across all the different target machines, for later analysis. (same idea than what is done with the endianness of network) Regards, Remi Andruccioli=
