Front-end compatibility
When migrating to Genero Business Development Language (BDL), you must use one of the Genero front-ends; the WTK, WebFE and JavaFE front-ends are not compatible with the Genero fglrun runtime system. Note also that the UNIX™ version of Genero does not include the fglX11d front-end any longer. You must use the GDC front-end on UNIX.
