  Use the RES\multilang.exe wizard to generate multi-language resource file. It will create the frxMultiLang.pas unit with the following contents:
  
  unit frxMultiLang;
  
  interface
  
  procedure SetEnglishResources;
  procedure SetRussianResources;
  
  ...
  
  You need to include this unit into your app. To switch the resources, just call one of SetXXXResources methods.
