What's New in Base SAS 9.4-经管之家官网！

Procedures Enhancements

• The APPEND, COPY, and CONTENTS statements support AES encryption.
• The CONTENTS statement prints the International Components for Unicode (ICU) revision number.
• The DATASETS procedure supports extended attributes.
• The DELETE procedure enables you to delete SAS files from the disk or tape on which it is stored.
• The JSON procedure reads data from a SAS data set and writes the data to an external file in JSON representation.
• The MIGRATE procedure supports extended attributes.
• The OPTIONS procedure supports the new LISTOPTSAVE option which lists the system options that can be saved by using the OPTSAVE procedure or the DMOPTSAVE command.
• The PRINT procedure support the SUMLABEL= option and the GRANDTOTAL_LABEL= option enable you to specify labels for the BY group total and grand total values.
• The PROC PRINTTO PRINT= statement opens the LISTING destination. You no longer need to specify the ODS LISTING statement before you use the PRINTTO procedure.
• In-Database processing for PROC REPORT now supports the Aster, Greenplum, and HADOOP database management systems. Also, NOWINDOWS is now the default windowing environment for PROC REPORT
• The XSL procedure now provides the PARAMETER statement to pass a parameter value to an XSL style sheet.
  

Other Enhancements

• The default value of the EXTENDOBSCOUNTER= data set option has been changed to YES.
• The default value of the YEARCUTOFF= system option has been changed to 1926.
• The LIBNAME statement for the XMLV2 engine nickname supports the PREFIXATTRIBUTES= option.
  

Increased Security

• SAS/SECURE is a product within the SAS System, and it is now included with Base SAS. A separate license for SAS/SECURE is no longer required. This change makes strong encryption available in all deployments (except where prohibited by import restrictions).
• SAS/SECURE increases data security by using the industry standard Advanced Encryption Standard (AES) with 64-bit salt. See Encryption in SAS 9.4.
• The enhanced ENCRYPT= data set option now supports AES encryption. This enables you to use the AES algorithm for stronger encryption.
• Data sets in a metadata repository can be secured by placing them in a metadata-bound library. A metadata-bound library is a physical library that is tied to a corresponding metadata object.
  

National Language Support (NLS)

• SAS can now process data by using a time zone other than your local time zone. New time zone formats use the ISO 8601 standard to format dates, times, and datetime values by using Universal Coordinate Time (UTC).
• New time zone functions enable you to determine time zones and time zone offsets, and to convert datetime values between SAS and UTC.
• A new SAS datetime constant enables a SAS datetime value to have a time zone offset.
