| 1. | Program headers, as comment blocks, should always be included in SAS programs to describe the function of the program, and the data input to, and output from, the program. |
| 2. | Distinct sections of SAS code should be separated using descriptive comment blocks. |
| 3. | Indenting of SAS code lines should be used to indicate loops, nested code and other code constructs. |
| 4. | Variables and SAS datasets should be given meaningful names. |
