Section 5.3.2 says:

<number> ::= any decimal integer 1 through 255

It should say:

<number> ::= any decimal integer 0 through 255

Notes:

if 0 is not allowed, one cannot even represent 127.0.0.1 with
<host-number> ::= <number>,<number>,<number>,<number>

[Verifier Note: This does allow syntactically for nonsense values for <byte-size>, <port-number>, and <host-number>, but this was also true in the current syntax.]

Section 5.4 says:

                  200
                  500, 501, 502, 421, 530, 550

It should say:

                  500, 501, 502, 421, 530, 550

Notes:

The reply codes for CDUP are supposed to be identical to those of CWD according to Appendix II - Reply Codes. Thus, the proper return code for a successful CDUP should be 250 - Requested file action okay, not 200 - Command okay.

Section APPENDIX II says:

...
         CWD overrainbow
         431 No such directory

...
         CWD overrainbow
         550 No such directory

Notes:

Reply codes in the examples are not conform to the specification :
200 is not a valid code for CWD. It should be 250 (Requested file action okay, completed).
431 is not a valid code for CWD and is not defined in the RFC. It should be 550 (Requested file action not taken).

Section 5.2 says:

The direction of the transfer and the port used will be determined by the FTP service command.

It should say:

The direction of the transfer will be determined by the FTP service command.

Notes:

Per RFC 1123 (section "4.1.2.12 Connections"), the clause "and the port used" was a remnant of an earlier version of the standard, and ought to have been removed during the rewrite that produced RFC 959. Admittedly, RFC 1123 does only use the term "should" in saying to ignore the wording, as the behaviour described had been correct at one time -- but that time was meant to have ended 38 years ago. For the few brave souls who attempt to program FTP support in the modern day, this really ought to explicitly annotate the actual RFC.

Section 4.1.3 says:

In the description of the SYST command, the second sentence reads:

"The reply shall have as its first
word one of the system names listed in the current version
of the Assigned Numbers document [4]."

Where [4] points to the then-current RFC 943.

It should say:

The reply shall have as its first
word one of the system names listed in the current version
of the IANA "Operating System Names" Registry (<http://www.iana.org/assignments/operating-system-names> at
the time of this writing)

Notes:

RFC 943 was several times obsolete by the time the community discontinued regular updates to the "Assigned Numbers" RFCs (see RFC 3232, January 2002). The clear intent was that SYST be able to use operating system names from that registry. An erratum pointing to the registry itself may aid the confused as well as providing better tracking and serving as placeholder in case RFC 959 is ever updated.

Section 2.1 says:

      This current edition of the FTP specification is intended to
      correct some minor documentation errors, to improve the
      explanation of some protocol features, and to add some new
      optional commands.

      In particular, the following new optional commands are included in
      this edition of the specification:

         CDUP - Change to Parent Directory

         SMNT - Structure Mount

         STOU - Store Unique

         RMD - Remove Directory

         MKD - Make Directory

         PWD - Print Directory

         SYST - System

      This specification is compatible with the previous edition.  A
      program implemented in conformance to the previous specification
      should automatically be in conformance to this specification.

      All commands for the mail service are now obsolete and removed
      from this FTP specification. These commands are MLFL, MAIL,
      MSND, MSOM, MSAM, MRSQ, MRCP.  The return codes used for the
      mail service are also removed: 151, 152, 354.  Return code 215
      is reassigned here to another use.

      This specification is compatible with the previous edition.  A
      program implemented in conformance to the previous specification
      should automatically be in conformance to this specification, as
      long as it does not use the obsolete commands.

Notes:

Before claiming the specification is compliant with the previous version, noting what is added is not enough; we need to note what was removed also.

Section 3.3 says:

      Reuse of the Data Connection:  When using the stream mode of data
      transfer the end of the file must be indicated by closing the
      connection.  This causes a problem if multiple files are to be
      transfered in the session, due to need for TCP to hold the
      connection record for a time out period to guarantee the reliable
      communication.  Thus the connection can not be reopened at once.

Notes:

Two Sections in the RFC have the same number in the document whereas the The Carriage Control (ASA) should have 3.1.1.5.3. in the structure of the RFC document since its a third format of the possible value for the parameter mention in the statement "Therefore, these types have a second parameter specifying one of the following three formats" ATM it has the same 3.1.1.5.2. as the Telnet Format Controls.

Section 5.3.2 says:

<number> ::= any decimal integer 1 through 255

It should say:

<byte-size> ::= any decimal integer 1 through 255
[...]
<number> ::= any decimal integer 0 through 255

Notes:

I agree with the author of errata ID 3039 that excluding 0 from <number> is problematic. However, <number> is also used in the definition of <byte-size>. The text in 3.1.1.4 says that"The value of Byte size must be a decimal integer; there is no default value." Strictly speaking, then, 0 is a valid value but I don't see how zero could lead to a sensible result. Indeed the term "decimal integer" is undefined so perhaps negative values are permissible?
--VERIFIER NOTES--
See Erratum 3039. Though the change there does allow for nonsense values for <byte-size>, so does the current syntax in 959. I have accepted 3039 and rejected this as duplicate.

Notes:

The reply code for 227 in sections 4.2.1 and 4.2.2. shows <host-port> surrounded by parenthesis with a period at the end, whereas the example in section 5.2 does not.
--VERIFIER NOTES--
As Section 4.2 states, only the numeric value of the reply code is significant to the protocol; the text is intended for human readers. The parentheses and period are not significant.
