Going Old School

Recommended Posts

I have an old DOS application (yes DOS, not command line) that I need to run on a contemporary OS. Presently this requires setting the following lines in Config.NT:

dos=high, umb
device=%SystemRoot%\system32\emm386.exe NOEMS

I'd like to call this application without having to set those options that way ... like set up the environment and make the call to the executable all in one script. Anyone have any ideas?

Short of parsing the Config.NT to see if it was there, adding it if it was not, and then removing the lines again after I have not been able to find anything appropriate.

Have you tried running it in DOSBox?

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Also see EnvSet() in the help file. The environment variables you set will only last as long as the script is running so you will have to use RunWait() to run the app.


EnvSet ( "dos", "high, umb")
EnvSet ( "files", "125")
EnvSet ( "device", "himem.sys"); I'm not sure if you need the path for the 2 devices or not
EnvSet ( "device", "emm386.exe NOEMS")
