Macro language is a facility for generating SAS code programmatically. The macro language variables, functions and statements are interpreted by the macro processor as a SAS program is being parsed at compile time. The text that is generated (resolved) by the macro language can then be interpreted as SAS code and run by the SAS compiler.
In SAS code, macro variables begin with an ampersand symbol ( & ) and end with a period (.) or before any character that cannot be used in a variable name. Meanwhile macro functions and macro statements start with a percent symbol ( % ) and end with a closing parenthesis ( ) ) for functions or a semicolon ( ; ) for statements.
