WHAT IS THIS??

It is a SAS NOTE that comes when a non-blank character follows immediately after a closing (double or single) quote of a string literal (constant), as such characters might carry a special meaning.

Such a NOTE often is the signal that you have unbalanced quotes in your code, so a string was not terminated properly.

Inspect your code thoroughly, and restart your server connection, so the state of the SAS process is reset.
