The assembler will, of course, only support the mode that it can access.  DOS
can not (as of ver 3.x) access the proteced mode, so having the assembler
support it would be foolish.  Xenix, which works in protected mode, supports
the protected mode commands, but not the real mode.  You don't get both in
either, because of the way the chip is designed.  When DOS 5.x comes out
(if it ever does), it will support multi-tasking & multi-users, then it will
support the protected mode and not the real.
