Thanks least this helps quite a bit. How do I get to DOS from 98 or XP?. Do I use the command line or do I have to boot to dos. One more thing, after I'm in DOS how do I run a program. This probably seems pretty elementary but I never have had any real need to learn DOS until now. I also have found a few helpful sites: hxxp://www.uv.tietgen.dk/staff/mlha/index.htm. Lots of good programming info there. Once again thanks for your help, it is very much appreciated.
