## Command 'virtual'

| This command is used to set the virtual DataView mode. When the virtual mode is set, all widgets are opened as virtual (hidden) widgets.
| This command must always called in pairs (acitvation/de-activation); however, nested calls are permitted. This command could be compared with the function 'wdg_set_vir' of the DataView programming interface. This command must not be called with a conditional instruction.
