Support for languages other than U.S. English may be provided in help files by specifying the /COUNTRY, /CODEPAGE and /LANGUAGE parameters in the IPFC command. These parameters affect the collating sequence used when creating a table of contents or index, and the titles displayed for note (:nt), warning (:warning) and caution (:caution) tags.
These parameters and the use of national languages in help windows and online documentation is described in more detail in the IBM OS/2 Version 2.0 Information Presentation Reference.
