The manuals say so, but the OS disagrees. COMMAND.COM doesn't like
it, though. Note that you're reading the *user guide*, which isn't
exactly a spec.

MS-DOS will, in fact, let you create a filename with spaces in them,
although I believe it will not let the space be the first character
(and as the last character it gets cropped.)
