'''CBM''' ("Command Bar Menu") is a part of [[FutureOS|FutureOS]]. It is not completely part of the core ROMs, because it needs a high degree of flexibility to serve very different applications. CBM provides an consistent user-interface for all applications. You can use hierarchical pull-down menues to select files or functions. The interaction by the [[FutureOS|FutureOS]] desktop is done by using the OK icon. Since version 1.8 hot keys have been added.
The flexible part of CBM is provided as well documented Z80 source code that can be used to create new applications for [[FutureOS|FutureOS]]. The other part of CBM is integrated in the core ROMs of FutureOS. The source code and some examples can be downloaded from the official FutureOS-Homepage. Therefore it's possible to adapt / use CBM for any of your self written FutureOS applications.
