In order to have PxPlus use a DLL library it must be named 'PLUSLIB.DLL' and exist within the same directory that the PxPlus.exe resides in.   The DLL will contain each of the PxPlus programs and data files that you need for your application as windows Resources.

During system initialization, PxPlus will open the DLL and build a list of the files/programs that is contains.   Whenever your application references any of the files that are contained within the library, the version in the library will be used regardless as the value set in PREFIX.

File names within the library are case insensitive and all slashes will be converted to a forward slash.

In order to determine if the program/file is being accessed from the DLL Library, the full pathname for the program/file will contain "[res]" as a prefix.
