Yes, but the proper syntax is:

 mov byte ptr [100],0
 mov word ptr [100],0
 mov dword ptr [100],0

You can abbreviate "byte ptr" to "by", "word ptr"
to "wo", and "dword ptr" to "dw".

See NWDOSTIP.TXT (MPDOSTIP.ZIP) for details.

No, unlike MS-DOS DEBUG, the DR-DOS DEBUG requires
a space between the command and its arguments.
I do not think this will change, because even if
MS-DOS DEBUG allows this, itīs invalid syntax and
may cause problems when extending support for new
processors. Mind that the MS-DOS DEBUG only supports
the 808x opcodes, while the DR-DOs DEBUG already
supports all commands (available under DOS) up to
the Pentium.

Do you have a special need for this?

Greetings,

 Matthias
