When incorrect operation is done or help information is requested from the user, application program needs to provide the help information to its user. An application program may provide its own help function or it can use the system provides help function. For example the IPF utility or message file mechanism. The help function and mechanism are recommended because they are already enabled to support DBCS in the DBCS OS/2. The help information data should be separated from the program code, so that they can be translated and included easily later on. See the Single Module for the considerations of MRI and PII, and the IPFC Information Presentation Facility Compiler for the information of creating help information for a PM application programs.
