The DOS Settings feature of MVDM provides the user with the ability to selectively configure and tune the virtual DOS machine environment to meet the requirements of particular applications. Since some DOS applications require certain features while other applications operate better without them, a VDM may be individually configured to provide the optimum execution environment for the application which will run within it.
DOS settings may be set by the user when adding an application to a group on the desktop, or in certain cases, during execution while an application is running within the virtual DOS machine. In the case where a VDM is created by another process using a DosStartSession() function call, a buffer may be provided containing the required DOS settings and their values.
