Complete SAS Programming Guide - Learn SAS and Become a Data Ninja - Index Options

The video tutorial discusses creating an index and explores two options: 'no miss' and 'unique'. The 'no miss' option helps save space by not maintaining missing values in the index, which is useful when the index variable has many missing values. The 'unique' option requires key variables to be unique, preventing duplicate values, which is important when updating observations. Examples are provided to illustrate the use of these options.
