If I type "command/c ver" to get DR DOS to ]tell me, it says "Incorrect DOS Version". Just a quick comment about DRDOS 5.0. There are two ways that *DOS* reports its version. 1) The VER command. 2) The interrupt 21 function (don't remember the subfunction, besides, that not important right now). 1) The DRDOS 5.0 VER command reports the value of the environment variable VER. 2) The DOS interrupt reports 3.3 to allow applications who are "picky" to work. Now the MS has released a good idea with "setver," I suspect we will adopt this method for changing this reporting mechanism soon. -- John "Frotz" Fa'atuai frotz@dri.com (email@domain) Digital Research, Inc. uunet!drivax!frotz (bang!email) c/o MIS Dept. 408/647-6570 or 408/646-6287 (vmail) 80 Garden Court, CompRm 408/649-3896 (phone) Monterey, CA 93940 408/646-6248 (fax)
