Macro Language Elements
The SAS macro language consists of statements, functions, and automatic macro
variables. This section defines and lists these elements.
• “Macro Statements” on page 158
• “Macro Functions” on page 160
• “Automatic Macro Variables” on page 167
Also covered are the interfaces to the macro facility provided by Base SAS software, the
SQL procedure, and SAS Component Language as well as selected autocall macros and
macro system options.
