Complete SAS Programming Guide - Learn SAS and Become a Data Ninja - Automatic Variables

The video tutorial explains the concept of automatic variables, which operate in the background to assist with error handling in data processing. It focuses on two specific automatic variables, _error_ and another unnamed variable, which help identify and log errors in data. The tutorial demonstrates how to use these variables in combination with the put statement to make error messages clearer and more explicit. An example is provided to show how errors, such as input data errors, conversion errors, or math errors, can be identified and logged effectively.
