What's New in SAS 9.2 National Language Support (NLS) Reference Guide
| Overview |
In this release, SAS has expanded the scope and capabilities of National Language Support (NLS). NLS is a set of features that enable a software product to function properly in every global market for which the product is targeted. SAS contains NLS features to ensure that you can write SAS applications that conform to local language conventions. Typically, software that is written in the English language works well for users who use the English language and data that is formatted using the conventions that are observed in the United States. However, without NLS, these products might not work as well for users in other regions of the world. NLS in SAS enables users in regions such as Asia and Europe to process data successfully in their native languages and environments.
This topic describes the changes and enhancements that have been made to the NLS documentation and features.

NLDATMMN converts the SAS datetime value to the datetime value of the specified locale, and then writes the value as the name of the month.
NLDATMWN converts a SAS datetime value to the datetime value of the specified locale, and then writes the value as the day of the week.
NLDATMYQ converts the SAS datetime value to the datetime value of the specified locale, and then writes the value as the year and the quarter of the year.
NLDATMYR converts the SAS datetime value to the datetime value of the specified locale, and then writes the value as the year.
NLDATMYW converts the SAS datetime value to the datetime value of the specified locale, and then writes the value as the year and the name of the week.
