looks like a little misunderstanding about use of the LIBNAME statement is causing the problem. Assume I have a directory on my PC called ANDREW there are several SAS data sets in this directory (and, for the sake of argument, some Excel spreadsheets, Powerpoint presentations and word documents). For our purposes, the SAS data sets are ONE.ssd, TWO.ssd and THREE.ssd

The LIBNAME statement points to a physical file location containing one or more SAS datasets. The name of the LIBNAME (see below) acts as a "handle" which allows the user to access _all_ the SAS data sets in the library.

You _don't specify_ the file extension (i.e,, the "ssd" or "sd2") in the libname statement.

Using my example above, here is a LIBNAME statement which would make the SAS data sets in directory ANDREW available to me for use in a SAS program:

LIBNAME MYFILES 'C:\Andrew';

having assigned LIBREF MYFILES to the SAS data library ANDREW, I can go to work.

Here is an example:

PROC FREQ DATA=MYFILES.ONE; TABLES INC * SEX/EXPECTED; RUN;

I hope this helps! **************************************** Andrew H.
