filetype -- change file's type (& auxtype)

syntax:  filetype <pathname> <filetype> [-x<integer>]

ex:      filetype myfile sys
         filetype ? bin -x$2000

Changes the file type (NOT the storage type) of a file.  If
-x is given, also sets the auxiliary type (subtype) as
specified.

NOTE:  Although you can change a DIR file into another type,
       and you can change a non-DIR file into a DIR file,
       this changes ONLY the file type and will cause much
       confusion--it is not recommended.  (The storage type
       is not affected.)
