The primary documentation for SAS on UNIX is the SAS OnlineDoc(tm) which is available at the USC Web site (restricted to computers registered in the USC domain 128.125.; see the end of this document for details.) Older documentation for Version 6 of the SAS System also is available, and is still applicable, though newer features obviously are not included. At the end of this document you will find a list of relevant SAS documentation and where to find it.
