o  Quotation Marks
       Use quotation marks (" ") for UNIX host path names that
       include slashes (/), such as user/simms/offers, and for
       user/host specifications that include the username@hostname
       syntax.
       If the remote host uses case-sensitive user names and
       passwords, use quotation marks in the following situations:
       o  User names and passwords are mixed case.
       o  Passwords are lowercase.
       o  User names are uppercase, unless you use the /NOLOWERCASE
          qualifier.
    o  Qualifiers
       You can specify R command qualifiers in either of two ways:
       o  Enter the qualifiers on the command line, as follows:
          $ RCP /LOG TRANQUIL:VULTURES []
          $ RSH /EIGHTBIT /ESCAPE_CHAR="+" /TRUNCATE HERON CAT -N STREAMS
       o  Add the same information to your LOGIN.COM file, as shown
          in the following example:
          $ ! To customize my R commands:
          $ !
          $ RCP :== RCP /LOG
          $ RLOGIN :== RLOGIN /EIGHTBIT/ESCAPE_CHAR="+" /TRUNCATE_USER_NAME
          $ RSH :== RSH /EIGHTBIT /ESCAPE_CHAR="+" /TRUNCATE_USER_NAME
          $ !
