//
// Flags for _SHELL_SuggestSingleMSDOSMode
//
// SSAMFLAG_KILLVM
//        A fatal application error has occurred.  Display a warning box
//        unconditionally.  Regardless of the answer, terminate the VM.
//        If this bit is set, the call does not return.
//
//  SSAMFLAG_TIMER
//        Not used.  Sorry.
//
//  SSAM_REQREALMODE
//        App requires *real* mode, not V86 mode, not EMM stuff, not
//        QEMM.  Just pure unadulterated real mode.  Also known as
//        SSAM_COMANCHE, because Comanche does an "lgdt" to enter
//        protected mode without checking if it is safe to do so.
//        This flag is inspected by AppWiz to decide how to set up
//        the config.sys and autoexec.bat.
//
//  SSAM_KILLUNLESSTOLD
//        Suggest Single MS-DOS mode (unless suppressed via PIF), and
//        if the answer is "Okay", then kill the VM.  If the user
//        says, "Keep running", then let it stay.
//
//  SSAM_FROMREGLIST
//        This app was run from a command prompt, triggered by registry
//        settings.  Just re-execute it in its own VM so that APPS.INF
//        settings will take effect.
//
//  SSAM_FAILEDAPI
//        This app just made an API call that was unsuccessful or
//        unsupported.  If the app terminates within 0.1 second,
//        then suggest single-app mode.  If the app continues
//        execution, then don't suggest.
