How do I put a space in the  part of a Xtern_Dos menu item ?

Eg, in "menus.ctl":

==============================================================================
Xtern_Dos   C:\GAMES\KNK\KNK.BAT DORINFO1.DEF   normal   "Kannons
& Katapults"
==============================================================================

The above example will give an "Invalid ACS definition:
'DORINFO1.DEF'" error (Maximus treats the "dorinfo1.def" as
the access definition rather than a parameter to "KNK.BAT"). I
want Maximus to treat "dorinfo1.def" as a parameter to the
calling batch file.

I don't want to use a MECCA file.

I think there's a trick to do this or some special character sequence for
blank spaces in a *.ctl (or that could just be my imagination). The closest
thing I can find in the documentation is "%U" but this is for
underlines.
