R:BASE must be used to develop the database and custom application. The R:BASE version and build used to create and customize the application must also be used to run the application. For example. if the users are running the custom application with R:BASE 11, the database and applications must have been developed with R:BASE 11. Along with the R:BASE product version, the product build should also match between the development environment and end user computers. For example, if the development computer is running R:BASE 11 Build: 11.0.1.20919, the end users should also run the exact build. To verify the version and build for an R:BASE installation, you can type SHOW VERSION at the R> Prompt.
R>SHOW VERSION
R:BASE 11, U.S. Version, Build: 11.0.1.20919
R:BASE Plugins
R:BASE plugins can be used to enhance, or extend R:BASE operations. R:BASE 9.x and higher versions use plugins with the .RBM file extension. R:BASE 7.x and Turbo V-8 versions use the .RBL file extension. The R:BASE plugin version must match the R:BASE software version in order to work properly.
