Look at this paper :
http://ftp.sas.com/techsup/download/sample/unix/dstep/uncompress.html

or this one :
http://www.albany.edu/csda/comprw.pdf

Please read carefully the important restriction mentioned in both paper.

The short answer is no, you can't.

The longer answer is that you can read it as a bit stream, but not as a SAS data set.  SAS requires direct access, and that in turn requires that the whole data be available on disk at the same time.

Subject: [SAS-L] Read the compressed (abc.sas7bdat.Z) SAS dataset directly

Hi All,

Is there any way to read the compressed sas dataset directly in unix. I have
a compressed sas dataset like abc.sas7bdat.Z. I want to read and do some
operations on this data wihout uncompressing the actual dataset. Is there
any way to do this?

I have searched the archieve but have not found anything specific( a piece
of code) :(.

Thanks,
Kunal
