Jie:

How you process this file depends on how it was created.

If it is compressed via third-party compression tools (eg: 'pkzip', 'winzip' on PC, 'compress', 'gzip', or 'tar' on UNIX), you need to uncompress with the appropriate utility. If the file is a 'compressed' SAS data set, SAS manages compression automatically.

You don't mention what platform you are on or what version of SAS, or where the data are coming from. You will need to ask the supplier of the data for more information, specifically: - what kind of data set this is (eg: SAS dataset, SAS transport dataset, ASCII/EBCDIC output) - what platform it was created on (eg: PC, UNIX, Mac, IBM Mainframe) - what version of SAS it was created by.
