Translating the message text
All File Manager Base function messages are stored in the FMN0MENU source member.
This CSECT is part of the root module so that an English version of the messages is always available. In addition, all messages used by File Manager under ISPF are provided in the library, FMN.SFMNMENU. Using both FMN0MENU and members in FMN.SFMNMENU, you can provide your own set of translated messages in another language. To use the messages you have translated, see Using the translated messages and panels.
To provide translated versions of the messages, you must provide a version of FMN0MENU for your language, as described in Providing a multicultural version of FMN0MENU, and provide translated versions of the appropriate members in FMN.SFMNMENU, as described in Translating the ISPF messages text.
You should not need to provide a Japanese version of the messages if you have installed the File Manager Japanese component.
