Think about you have a great assistant that will help you write the SAS programs. Your helper willingly and unfailingly uses your instructions allowing you to will leave your site and go to other tasks. Repetitive encoding assignments just like multiple PROC TABULATE tables, where the just difference among one table and the following is the classification variable, are delegated to your assistant. Jobs that require you to run a few steps, review the output, then run additional steps depending on the output are generally not difficult; they can be, however , labor intensive. With guidance on choice of subsequent measures, your assistant easily grips the work. Possibly having your assistant do straightforward tasks just like editing data in SUBJECT statements makes your job much easier.

Actually, you already have a SAS programming assistant: the BARRIERE macro center. The OBSTACLE macro service can carry out all the tasks above and even more. To have the macro facility do the job, you first need to be aware of how to contact the macro facility. That's the purpose of this guide: to show you ways to speak with the OBSTACLE macro facility so that your BARRIERE programming may become more effective and efficient.
