It Works For Me, but as mentioned above, I'm not a gamer, and don't do the sorts of things in DOS NT won't let you do, NTVDM provides a virtual DOS environment fro running 16 bit apps. When you run a DOS app, NTVDM is run, and a copy of COMMAND.COM is spawned to run the DOS app. All of the character mode stuff I run works fine. The thing to remember is that a app run in NTVDM is a process running in a 32 bit environment. If you shell out od the DOS app to a command line, you're t talking to CMD.EXE, not COMMAND.COM One of the old DOS apps I still run is Eric Meyer's VDE. VDE is an editor that began under CP/M as a single-file alternative to the WordStar word processor, Eric later moved development to MS-DOS. VDE is freeware these days, but still maintained and supported. VDE has an Alt-R command for shelling to external processes. Press Alt-R and you get a command line in VDE. Enter a command on that line and press Enter and VDE attempts to run what you entered. Just press Enter and VDE spawns a shell. The shell is CMD, not COMMAND. I discovered that you could use the CMD START builtin to do things like run a process in a new window from within VDE. Exit the process in the new window, and you were back in the VDE session. This provides the ability to use other apps called from VDE to perform operations on the text you are editing that VDE itself can't do, Win2K/WinXP both have AUTOEXEC.NT and CONFIG.NT files. These are used to configure the NTVDM environment. By default they don't do anything, but you can customize them as desired. If you do that, it affects *all* NTVDM sessions. You have to be careful about this. If you run your DOS app from a batch file, settings in AUTOEXEC.NT will override settings in the batch file, which is probably not what you want. This bit me till I figured out what was going on and reserved app specific stuff like PATH for the batch file and didn't try to diddle it in AUTOEXEC.NT. ______ Dennis https://plus.google.com/u/0/105128793974319004519 ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
