     The commands,

       ENCODING BASE64
       MODE BLOCK
       SEND [.GIF]BOATS*.GIF
       SEND/MODE=TEXT [GIF]INDEX.TXT

     set the default encoding to BASE64 and the default file
     reading mode to BLOCK. Any files matching the specification
     [GIF]BOATS*.GIF will be sent using these defaults. However, the
     file [GIF]INDEX.TXT will be sent as an ordinary text file owing
     to the use of the /MODE=TEXT qualifier.
