The SAS log has three types of

messages about your program.

Errors These messages are hard to ignore , because not only dothey appear in red on your screen, but also your program will notrun with errors. Usually errors are some type of Syntax or spellingmistake.

Warnings These are less serious than errors because yourprogram will run with warnings. However, a warning might meanthat SAS did something you did not intend.

Notes These are less straightforward than either errors orwarnings. They provide information , such as telling you theexecution time of each step in your program.
