Prior to SAS Version 8, SAS incorrectly issued a single occurrence of a given error message even after the user had specified OPTIONS ERRORS=0. In addition, SAS failed to produce the informational message after the error was written to the SAS Log:
Beginning in SAS Version 8, SAS does not issue any error messages when ERRORS=0 is in effect. SAS also correctly produces the LIMIT SET message after the first occurrence of a given error message.
For more information about the ERRORS=0 option and changes made beginning with SAS® 9.1, see Usage Note 14598, "LIMIT SET message produced with OPTIONS ERRORS=0."
For more information about the ERRORS= option and changes made beginning with SAS® 9.2 TS2M0, see Usage Note 32944,"The log message seen as the result of using the ERRORS= option is a warning message in SAS® 9.2."
