Options such as ERRORS=, NONOTES, and NOSOURCE enable you to suppress information that is written to the SAS log. However, there is not an option that turns off all warning messages.

In the SAS^® Macro Language, the options NOSERROR and NOMERROR might also prove helpful. The NOSERROR option prevents warning messages when the macro processor cannot match a macro variable reference to an existing macro variable. The NOMERROR option prevents warning messages when the macro processor cannot match a macro reference to a compiled macro.

If it is important that the SAS log window not contain any warnings, use the PRINTTO procedure or the system option ALTLOG to redirect the .log information to an external file.
