Once you isolate MRI from your source code, the next step is to isolate MRI from the executable module. Usually, the MRI is generated as a DLL (Dynamic Link Library) and the program will load a proper MRI at runtime by DosLoadModule API.

In order to determine in which language MRI should be used, you can utilize system APIs provided to obtain the runtime information described in Determining runtime code page and country code.

There are three levels of implementation to determine a language for MRI as follows:

Let a user choose a language at installation of an application program
Allow a user to choose it at the start-up of an application program
Automatically set up the default value based on the current process code page and allow a user to override it at the start-up of an application program.

The first one is the easiest to implement; the last one gives the widest freedom to a user but requires the largest effort to implement. In any case, we highly recommend to include English MRI in your program diskettes in addition to its national-language translation so that a user has an option to select English MRI. This English facility is welcomed by users working at foreign-capitalized companies operating in Asian countries.
