The SAS System is an integrated suite of software for information delivery and analysis. Applications of the SAS System include executive information systems; data entry, retrieval, and management; report writing and graphics; statistical and mathematical analysis; business planning, forecasting, and decision support; operations research and project management; statistical quality improvement; computer performance evaluation; and applications development. SAS is very powerful, and is particularly useful for dealing with large data sets.
For the Fall 2008 semester in all ITC computer labs, Version 9.1.3 SP 4 of the SAS Education Analytical Suite (EAS) is installed on Microsoft Windows machines and Version 6.12 is installed on Apple Macintosh machines. SAS is NOT available for the Intel Mac. For a list of all lab locations and available software, visit the ITC Labs and Classrooms webpage.2. Via a UNIX account
3. Acquire a copy for your own computer(s)SAS Version 9.1.3 EAS for Unix is installed on blue.unix. Linux users may access SAS 9.1.3 and current versions of other ITC-licensed software by mounting ITC's /common directory according to instructions at http://www.itc.virginia.edu/desktop/linux/mount.html. To be able to use these systems, you must first acquire an account.
Important Note: SASŪ compatibility with Microsoft's Internet Explorer 7 has NOT been validated. Please read this article before installing SAS on your PC: http://www.itc.virginia.edu/research/news/newsletterJan07.html#sasie7
If you are faculty, staff, or a graduate student of the University, AND you have an office in Charlottesville where you work at least twice a week, you may obtain the site-licensed copy of SAS 9.1.3 for Windows, or SAS 6.12 for Macintosh for home or office use. SAS is NOT available for the Intel Mac. Users of Windows XP HOME edition cannot install SAS 9.1.3. Rather you should request and install SAS version 8.2. For more information on system requirements and platforms see the system requirements. SAS may only be used while you are employed, or a registered student, at UVA.

If you have questions on usage, there are several options for helping yourself. Help from within SAS:In Unix, type man sas to access the manual pages for SAS On the web:
- SAS for Windows, Macintosh, and on Unix running in X-Windows mode: click on the Help option on the menu along the top of the screen.
- If SAS on Unix is invoked in full-screen interactive mode, you can use the SAS command HELP to get detailed information about using the Display Manager System as well as help with SAS procedures, commands, and syntax. To exit this mode, use the comma nd ENDSAS;.
Additionally, SAS Institute publishes a manual that details the operation of SAS on the RS/6000s called "The SAS Companion for the UNIX Environment and Derivatives" and is available for reference only in the Scholars' Lab or may be purchased directly from SAS Institute by telephoning (919) 677-8000. You can also purchase SAS manuals on-line directly from SAS, Inc. via the SAS bookstore.
- Online documentation is also available at SAS Online Documentation for Release 9.1.3.
- While on the UVA network or through UVa's VPN, you may access online help for SAS version 8. Most of this applies to version 9.x.
- You can access the training documents for Windows, Macintosh, and Unix referenced above.
- Online documentation is also available at SAS Online Documentation for Release 9.1.3.
- The ITCWeb document SAS on the RS/6000 provides additional details for running SAS on the RS/6000s.

Example SAS Files
SAS Institute provides a complete set of on-line example files that are discussed in their documentation, as well as providing example files for the most frequently requested questions that SAS receives. These sample files are located in the /sas/samples directory. Within the "/sas/samples" directory are six other directories for the various modules. For example, there is a "/sas/samples/base" directory that has the examples for the base module. These files can be copied to your own directory and run . The files are extensively annotated.Locally written sample programs will be placed in the directory, /research/sas/examples. Currently, files in that directory are:
datecalc.sas example on date conversion datecalc.lst results of datecalc.sas datecalc.log log file for datecalc.sas example1.sas example of a simple sas file example2.sas another example of a simple sas file sasdata.dat input file for example1.sas and example2.sas fig1.sas example for creating a postscript graph fig2.sas example for creating a tektronix graph import.sas example of importing a transport datase import.lst results of import.sas import.log log file for import.sas export.sas Export SAS dataset to transport DATA set statrain.data sample data file Other SAS Resources
