Compaq C Run-Time Library Utilities Reference Manual

This "Compaq C Run-Time Library Utilities Reference Manual" provides comprehensive information for programmers developing international software applications that manage localization and time zone data on OpenVMS Alpha 7.3 and VAX 7.3 systems.

The manual covers two main sets of utilities:

1. XPG4-Compliant Utilities:
   • GENCAT: Used for creating and invoking message catalogs.
   • ICONV: For performing codeset conversions between different character encodings.
   • LOCALE: For setting international environment logical names, compiling locale definition files, loading/unloading locales, and displaying locale information.
2. ZIC Utility: The Zone Information Compiler, which creates binary files containing time zone conversion information from source files.

It details the formats of locale definition source files (categorized into LCCOLLATE, LCCTYPE, LCMESSAGES, LCMONETARY, LCNUMERIC, and LCTIME), and character set description (charmap) files, which define character symbols as character encodings. The document concludes with a complete command reference for all these utilities.
