Sample 24674: Determining odd versus even using the MOD function
The Full Code tab has an example that uses the MOD function to output only even-numbered observations from the input data set.
The MOD function returns the remainder from the division of the first argument by the second argument. In this sample, the first argument to the function is the observation number and the second argument is 2. Setting the second argument to 2 will result in a remainder of 0 when the observation number is an even number.

/* A remainder of 0 indicates the observation number is even and the observation is output. */

The results of the MOD function can be used to determine whether a value is odd or even.
