'''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 server serve very different applications. CBM provides an consistent user-interface for all own programsapplications. You can use hierarchical pull-down menues to select files or functions. The interaction by the [[FutureOS|FutureOS]] desktop is done by a function which calls it by using the OK icon.
One half of CBM is provided as well documented Z80 source code that can be used to create new programs for [[FutureOS|FutureOS]]. The other half 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 programs.
