Is your dataset very narrow (i.e. only a few columns)? If so, then V9
compression might actually make the dataset bigger. V8 32bit SAS uses about
12 bytes/obs overhead to do the compression, while V9 64bit uses about 24
bytes/obs for overhead.

comes to orginal size?
Thanks for help, and Thanks for quick responses for all.
