You can use the rand() function in SAS to generate random numbers.

The following examples show how to use this function in practice.

**Example 1: Generate One Random Number**

The following code shows how to generate a single random integer in SAS between 1 and 10:

**/*create dataset with variable that contain random value*/
data my_data;
call streaminit(1); /*make this example reproducible*/
x = rand("integer", 1, 10);
output;
run;
/*view dataset*/
proc print data=my_data;
**

The random number between 1 and 10 turned out to be **9**.

Note that we used the **streaminit()** function to ensure that this example is reproducible. This means that each time we run this code, the random number will be 9.

Feel free to leave out the **streaminit()** function to produce a different random value each time you run the code.

**Example 2: Generate Variable with Several Random Numbers**

The following code shows how to generate a variable in SAS that contains 10 random values between 1 and 20:

/*create dataset with variable that contain random value*/ data my_data; call streaminit(10); do i = 1 to 10; x = rand("integer", 1, 20); output; end; run; /*view dataset*/ proc print data=my_data;

Notice that each of the values for the variable x are random integers between 1 and 20.

**Example 3: Generate Multiple Variables with Several Random Numbers**

The following code shows how to generate multiple variables in SAS that contain random values:

/*create dataset with variable that contain random value*/ data my_data; call streaminit(10); do i = 1 to 10; x = rand("integer", 1, 20); y = rand("integer", 50, 100); output; end; run; /*view dataset*/ proc print data=my_data;

The **x** variable contains 10 random integers between 1 and 20 while the **y** variable contains 10 random integers between 50 and 100.
