What Does the RANK Procedure Do? The RANK procedure computes ranks for one or more numeric variables across the observations of a SAS data set and writes the ranks to a new SAS data set. PROC RANK by itself produces no printed output.
How does Nodupkey work in SAS?
The NODUPKEY option removes duplicate observations where value of a variable listed in BY statement is repeated while NODUP option removes duplicate observations where values in all the variables are repeated (identical observations).
Can you sort by two variables in SAS?
SAS allows multiple variable sorting, so we can sort multiple variables at the same time.
How do I sort multiple variables in SAS?
You can order a SAS dataset by multiple variables with the PROC SORT procedure. In the BY statement, you specify the variables that define the order. The variables are separated by a blank. In the example below, we order the my_ds dataset by the variables var, var2, and var3, all in ascending order.
How do you sort data without using PROC sort?

What does ascending sort order mean?
The order in how information is sorted or arranged, ascending order is always arranged from lowest to highest . For example, “1, 2, 3, 4, 5” and “a, b, c, d, e, f” are both arranged in ascending order.
What is descending sort?
descending sort. [di′send·iŋ ′sȯrt] (computer science) The arranging of data records from high to low sequence (9 to 0, and Z to A). Arranging data from high to low sequence; for example, from Z to A or from 9 to 0.
What is ascending order in access?
When you perform a simple sort, you must specify the order in which you want Access to sort your records: Ascending order. This means that Access will arrange the records in order from lowest to highest. Descending order. This is the opposite of ascending order, and is sometimes called reverse order.
