%macro varlist()?

Hello team,

What does %macro varlist() do?

It starts the definition of a macro named Varlist.

The code between that statement and %mend; comprise the entire definition of a macro.

If there is no corresponding %mend; following and the code is executed you may place the SAS system into an unstable state depending on what you do as SAS is expecting an "%mend;" somewhere.

SAS macros are one way to generate other code or perform coded actions. Typically the () should contain parameter values that the code uses to generate different code. The code between %macro and %mend is only the definition and executing the code makes the compiled macro available for later use. To use the macro you would submit %varlist () . This tells SAS that you want to execute the code that the macro varlist defined.

Macro code is not a trivial exercise but not horrific either. But the more familiarity you have with SAS in general the more likely you can write a useful macro that actually works properly.

It has a %Mend, I didn't put it on my first post.
Thanks for the response.
