Thanks and regards. Ramon Riera. It is possible, but very hard to write, because DOS is not reentrant: https://en.wikipedia.org/wiki/Reentrancy_(computing) DOS have a call to quit a program, but leaving it in memory.... Terminate Stay Resident (TSR). But such programs must respect special rules to avoid DOS to crash. There was a program, DESKVIEW, that was making an OS that was reentrant... as far as I understand, that was running over a DOS. Making it easy to have more than one program running at a time. See https://en.wikipedia.org/wiki/DESQview I don't know how hard it would be to make FreeDOS reentrant... or what was the recent infos as I am mostly basing the info I give here to what I learns in the nineties. _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
