Hi, Eric Auer ! PS: XBDA and moving it is not necessarily trivial. Our EBDA mover is working flawlessly AFAICT.Old code of mine actually, written for MSDOS 5+ before MS introduced the switches=/E option (or before I was aware of the switch?). Last week when I had discovered that the

Bertho ???, You may call me Czerno, Herr Ehlert You can't escape having to explain what adverse effects you were evoking, now anyway. command.com is a 'normal' program. just allocating DOS memory will give you an environment at ~1800:0. not such a good idea. You are joking, Herr
