National Language Support Library Routines

The library routines for handling extended and multibyte character sets are divided into three categories:

• Locale Setting and Inquiry Routines to set locales (local code sets) and inquire about their current settings
• NLS Formatting Routines to format dates, currency, and numbers
• Multibyte Character Routines for using multi-byte characters

All of these routines are described in detail in the Language Reference, A to Z Reference.

In the descriptions that follow, function and parameter names are given with a mixture of upper- and lowercase letters. This is to make the names easier to understand. You can use any case for these names when writing your applications.
