Get An Animated Guide: The Map Of The Sas Macro Facility - Phuse Wiki

The macro facility enables you to assign a name to character strings or groups of SAS programming statements. You can work with the names that you created rather than with the text itself.

A macro language function processes one or more arguments and produces a result. You can use all macro functions in both macro definitions and open code. Macro functions include character functions, evaluation functions, and quoting functions.

To test a SAS macro the test frame has to check the log and all outputs of the test objective. The test run is successful if the outputs meet the expected results, and the log is clean and contains the expected information.

You can also use a %PUT Statement to view available macro variables. %PUT provides several options that enable you to view individual categories of macro variables.

The macro %VAREXIST checks to see if a specific variable exists on a specified data set. The name of the variable of interest is passed to the VARNUM function, which in turn returns the variable's position. If the variable does not exist on the data set the VARNUM function returns a 0.

The macro facility allows us to write macro code that instructs SAS® how to generate the more familiar open code found in DATA steps and PROCs. With such a tool, we can consolidate families of related programs, execute the same piece of code repetitively, and develop applications for others to use.

It enhances the SAS programming facilities and works with existing code. Macros can be used in the data step, in procedures, and Screen Control Language (SCL) code. The Macro facility works with all operating systems and comes as part of base SAS. It can be used as a way to create streamlined code.
