Purpose of the Macro Facility The macro facility is a text processing facility for automating and customizing SAS code. The macro facility helps minimize the amount of SAS code you must type to perform common tasks. The macro facility supports: symbolic substitution within SAS code automated production of SAS code dynamic generation of SAS code conditional construction of SAS code 1
Macro Variable References Macro variable references: begin with an ampersand (&) followed by a macro variable name Can appear anywhere in program Are not case sensitive Are also called symbolic references Represent macro triggers Are passed to the macro processor
The Macro Processor The macro processor executes macro triggers, including macro language statements, macro functions, macro calls, and macro variable resolution. Compiler Macro Processor Word Scanner Input Stack
Deleting User Deleting User- -Defined Macro Variables Defined Macro Variables The %SYMDEL statement deletes one or more user-defined macro variables from the global symbol table. General form of the %SYMDEL statement: %SYMDEL macro-variables; Example: Delete the macro variables OFFICE and UNITS. %symdel office units;
