  65 /*                      Reply Codes for MMDF
  66  *
  67  *  Based on: "Revised FTP Reply Codes", by Jon Postel & Nancy Neigus Arpanet
  68  *      RFC 640 / NIC 30843, in the "Arpanet Protocol Handbook", E.  Feinler
  69  *      and J. Postel (eds.), NIC 7104, Network Information Center, SRI
  70  *      International:  Menlo Park, CA.  (NTIS AD-A0038901)
  71  *
  72  *  Actual values are different, but scheme is same.  Codes must fit into
  73  *  8-bits (to pass on exit() calls); fields are packed 2-3-3 and interpreted
  74  *  as octal numbers.
  75  *
  76  *  Basic format:
  77  *
  78  *      0yz: positive completion; entire action done
  79  *      1yz: positive intermediate; only part done
  80  *      2yz: Transient negative completion; may work later
  81  *      3yz: Permanent negative completion; you lose forever
  82  *
  83  *      x0z: syntax
  84  *      x1z: general; doesn't fit any other category
  85  *      x2z: connections; truly transfer-related
  86  *      x3z: user/authentication/account
  87  *      x4x: mail
  88  *      x5z: file system
  89  *
  90  *      3-bit z field is unique to the reply.  In the following,
  91  *      the RP_xVAL defines are available for masking to obtain a field.
