The problem here is that if you don't use parse/all, the space is
ignored.
>> help parse
USAGE:
PARSE input rules /all /case
...
...
REFINEMENTS:
/all -- Parses all chars including spaces.
...
...
Try this:
bset: charset [ #"^(00)" - #"^(FF)" ]
parse/all " " [ some bset ]
Or if you don't want to have to type all those weird chars:
bset: complement charset ""
parse/all " " [ some bset ]
