MOVE  -  copy messages into another mail file, and delete in this one

Usage:  MOVE [/type] filename [message-sequence]
  Unless specified, /type is "/mbox" and message-sequence is "current".

The MOVE command copies messages to another mail file, and marks them as 
  deleted in the current mail file (compare to COPY).  

If the mail file named exists, MOVE adds copies of the messages to the end 
  of the file.  If the mail file does not exist, MOVE creates it, unless
  the variable auto-create-files is set to NO.  If a directory is not 
  specified with the filename, MOVE assumes the MAIL-DIRECTORY, which by 
  default is your home directory.

If a type is not specified, /mbox is used for new files and the existing
  type is retained for existing files.  Use the type /mbox unless you also 
  use another mail system that needs another format.  /babyl and /mtxt 
  are the other types. 
  
Examples:               
    MM>move oldmail                #moves the current message
    MM>move oldmail 1,3:6          #specifying messages by number
    MM>move fred.mail from fred    #specifying messages from fred
