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