In reply to Daniel Adelsberg.

You'll notice that this article, which is about printing to the log, does not mention the RESET LOG statement. That's because that is ancient technology from before the days of ODS. The documentation for the RESET LOG statement says:

RESET LOG specifies whether output is routed to the SAS Log rather than to the LISTING destination. In the log, the results are interleaved with the statements and messages. The RESET LOG has no effect if the ODS LISTING destination is not active.

I don't think SAS Studio supports the LISTING destination, which is used for batch processing. To write a note to the log in SAS Studio, use the last technique in this article.
