Chandu,

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.

Good luck,

Gregg Snell

Hi SC,

If I am going to run with V8 tomorrow then the dataset will comes to orginal size?

Thanks for help, and Thanks for quick responses for all. Chandrasekhara Rao.
