Examples

     The commands,

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

     set the default reading mode to BLOCK and the default file
     encoding to BASE64. 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.
