IBM VM/CMS uses a rather strange convention for file names: the file extension
is separated from the name by a space.  This, of course, causes some problems
for the CLI, which are solved by the use of keywords.  (e.g. COPY FOO PASCAL
TO BAR PASCAL -- because there is a *third* part possible in a filename, the
"file mode" which identifies the virtual minidisk and some other attributes,
the keyword is required.)

This would, of course, be a bit more difficult on a Mac because in the VM/CMS
environment there is a maximum filename size in space-delimited words (three,
the name, type, and mode), so if a file type just happens to be "TO" you can
get around it by giving the full name including the file mode; the Mac doesn't
have this limitation, so it can't use this trick.  However, it does suggest
some possibilities for handling file names which can contain spaces.

One other possibility:  use multi-line commands.

Copy User HD:Communications:Telecommunicators:ZTerm:ZTerm 0.85
To User HD:Backups:ZTerm 0.85

From the keyboard, RETURN would make a continuation line and ENTER would
execute the constructed command.  One would need to indicate the beginning of
a command somehow, say by a blank line.  Multiple file names could be simply
listed one per line, or you could invent conjunctions:  "Copy file1 And file2
To Folder".

I would advise having a way to use SFGetFile on these, perhaps with a command-
key combination.  Paths can get pretty long, as shown above (the first path
really does exist on my hard drive).
