| Results Viewer | This window opens if there are printable results after running your program. |
| Results | This window provides some navigation through the output in the results viewer window. This is especially useful if you have written a program that produces a lot of output |
| Explorer | This is a navigation window, giving you access to your files and data sets. |

| PROC step | This step uses a number of procedures used to analyze data. |
| PROC PRINT | this procedure is used to print data and intermediate or final results. |
| PROC MEANS | This calculates sample means and variance, among other things |
| PROC TTEST | This procedure conducts hypothesis tests. |
| PROC REG | This procedure is used to estimate regression models |
| PROC SGPLOT | This procedure can produce a wide range of graphs and data plots |
| 3 ways to run a program in SAS | 1) Click the little "runner" button in the toolbar at the top of the screen 2) Go through the menus run --> submit 3) Type submit in the command line, left of the toolbar buttons |
