The _NULL_ data set is often used when you want to execute DATA step code that displays a result, defines a macro variable, writes a text file, or makes calls to the EXECUTE subroutine. In SAS, the reserved keyword _NULL_ specifies a SAS data set that has no observations and no variables. The current observation is being held in the input buffer until the end of the record is reached. It tells SAS to not to read a new record when an INPUT statement is encountered.
