     While on any file, you may copy that file to:
          A) Another name, on the same drive/user

:Renaming Files

     The Rename command ('R') may be used to:
          A) Change the name of one file
          B) Change the names of many files
          C) Change the user number of one file
          D) Change the user number of many files

     To just change the name of one file, the syntax is simple:

  12« B0║ CDP▒    «      40╦ ║ r  New name, or *? CDP2
  12. B0: CDP2    .      40K :

     You may also change the user number of the file, as follows:

  12« B0║ CDP▒    «      40╦ ║ r  New name, or *? B1:CDP2
  12. B1: CDP1    .      40K :
