MVDM inserts a DOS Settings... menu item on the system menu for all VDMs. Selecting this menu item causes the DOS Settings dialog box to be displayed, which in turn allows the user to modify settings for the VDM. For full screen VDMs, the user must switch to the Presentation Manager Window List using the Ctrl+Esc key sequence, and display the context menu for the VDM session by clicking mouse button 2 on the VDM's entry in the Window List. The DOS Settings... option is displayed in the context menu.
Note that only those settings that have been registered as being modifiable at run time may be altered in this way; other settings are not presented in the dialog box.
