=== [[Image:CBM.png|thumb|right]]CBM - a menu system for FutureOS ===
The Command Bar Menu ('''CBM''') is a part of [[FutureOS|FutureOS]]. It provides an user-interface for all own programs. You can use hierarchical pull-down menues to select files or functions. Windows aren't used, because windows curtail the usable screen area. The interaction by the [[FutureOS|FutureOS]] desktop is done by a function which calls it by using the OK icon.
'''CBM ''' is not part of the ROM based 64 KB core OS itself. Its provided as Z80 source code that can be used to create new programs for [[FutureOS|FutureOS]]. The well documented source code is availablein the net. Therefore it's possible to adapt / use CBM for any of your self written FutureOS programs.
If When using CBM is used for most programs, then every these program can have nearly the same appearance. This makes it easier easy to work with different programs, because the generic appearence is the same and the basic functions are located at the same positions.
Examples for programs using CBM are the [[FuturePlayer|MP3-Player]], the Sprite Converter [[GMSK|GMSK]], the map and playground editor [[GSED|GSEd]], the sprite manager [[Kane|Kane]] and some other applications for [[FutureOS|FutureOS]].
