To initialize an application, Open Client and Open Server:
Use the SYBASE environment variable to determine the location of the Sybase installation directory.
Use the locale-specific POSIX environment variables LC_*, LANG, LC_ALL, and LC_COLLATE and the locales.dat file to determine what language, character set, and collating sequence the application uses.
Use the libtcl.cfg file to load the directory driver and security driver, as required.
