Front-ends can be extended with custom functions to access specific features.
It is possible to implement custom front-end functions to interface with platform-specific features, and use the feature from a Genero program through a front call. For example, you can implement a front-end function module interfacing with a bar code reader, to return bar codes to the Genero program.
This section describes how to implement your own front calls by front-end type. Because each front-end type uses different technologies, you must use native platform APIs to implement front calls.
