APpend subcommand

Purpose

Use the APpend subcommand to append a local data set to a remote host.

Format


>>-APpend--local_data_set--destination_file--------------------><

Parameters

local_data_set: The name of the data set on your local host to be appended.
destination_file: The name of the file on the remote host to which your data set is appended. If the destination file does not already exist at the remote host, a new file is created. If the server is a z/OS UNIX server, the local file can be appended to a z/OS® UNIX file or an MVS™ data set.

Examples

In the following example, an FTP command is issued from MVSXA2 to MVSXA3. MVSXA2 has a data set MVSUSER.FTP.EXAMPLE with one member. The member, APPEND01, contains:

;
; THIS FILE ORIGINALLY RESIDED IN MVSXA2, AND
; WILL BE APPENDED TO A FOREIGN FILE IN MVSXA3.
;

MVSXA3 has a data set, MVSUSER.FTP.EXAMPLE, with one member, APPEND02. The member contains:

;
; THIS FILE ORIGINALLY RESIDED IN MVSXA3, AND
; WILL BE USED TO RECEIVE ANOTHER FILE FROM MVSXA2.
;

  User:  append
System:    Usage: APPEND localfile foreignfile
           Command:
 
  User:  lpwd
System:    Local directory is MVSUSER.
           Command:
 
  User:  append 'mvsuser.ftp.example(append01)' 'mvsuser.ftp.example(append02)'
 System:   >>>SITE FIXrecfm 128 Lrecl=128 Recfm=FB BlockSize=6144
           200 Site command was accepted
           >>>PORT 1,1,2,2,4,16
           200 Port request OK.
           >>>APPE 'mvsuser.ftp.example(append02)'
           125 Appending to data set MVSUSER.FTP.EXAMPLE(APPEND02)
           250 Transfer completed successfully.
           520 bytes transferred in 1.100 seconds.
           Transfer rate 0.47 Kbytes/sec.
           Command:

Results:

The following information applies when the local_data_set value is a named pipe in the z/OS UNIX file system:
- FTP cannot send the named pipe until you start a process on the client host to write to the named pipe. If FTP is the first process to open the named pipe, it blocks until another process opens the named pipe for writing, or until the FIFOOPENTIME timer expires.
- Appending a named pipe to a remote file permanently removes data from the named pipe in the FTP client file system.
FTP maintains the attributes of a data set that is transmitted between a client and a server. However, when you use the APpend subcommand, FTP can truncate data records and you might lose data. If the data set name already exists at the receiving site and the logical record length (LRecl) of the data set at the receiving site is less than the LRecl of the transmitted data set, FTP truncates the transmitted data set.
If the remote host is an MVS or VM host, and if the data set on the remote host has a fixed-record format, the format and record length of the data set on the remote host are always preserved.
Records from the data set on your local host are truncated or padded with blank spaces when necessary.
To append to a file on a remote host, you must define a working directory on that host, and you must have write privileges to the files in that directory.
The z/OS FTP Server does not request that unused space be released from a data set created during APPEND processing. If you are using the z/OS FTP Server and want the Server to request that unused space be released on a newly-created data set, use the PUT subcommand instead of APPEND.
