SAS Software in UNIX Environments : Using SAS Files and External Files

UNIX operating systems now support files larger than two gigabytes. Therefore, SAS support for partitioned data sets is no longer needed and has been dropped from SAS software.
You can use UNIX wildcard characters to specify pathnames in the FILENAME, INFILE, and %INCLUDE statements and the INCLUDE command.
In Version 8, you can specify the FILELOCKS option in the LIBNAME statement. This library option allows you to control file locking on a per-library basis.
