Hi Sakib and those interested, Quote: It is a version of DOS made originally by Novell, who became Caldera, I think, and then part of that became Lineo You are very close. Caldera did spin off the Dr. DOS off to Lineo. However, I believe Caldera bought Dr. DOS from Novell when it was divesting itself of non-network related product. Dr. DOS was sold around the same time as Wordperfect Office and Paradox. Dr. DOS's Web site is www.drdos.com It is a shame I just found it after all these years, and now, they are discontinueing the support of this product. --- Ross Eadie Voice: (204) 339-5287
