Example: Creating the FTP input file (FTCPDMS)

The FTP input file must contain all the FTP client subcommands necessary to connect and log on to the FTP server, set up and complete the file transfers, close the connection, and end the client session. This example shows the subcommands used for transferring files to two different remote systems.

Note: By using the code examples, you agree to the terms of the Code license and disclaimer information.

The following explanation can help you to understand the FTP client subcommands shown in Figure 1. The line numbers on the display correspond to the numbers that follow.

0001
User ID and password for dummy connection within client system SYSNAM03.
0002
Close dummy connection on system SYSNAM03.
0003
Open control connection to RISC System/6000 SYSNAMRS.
0004
USER subcommand with user ID and password for SYSNAMRS.
Note: When running FTP in batch mode, the USER subcommand must follow an OPEN subcommand. Both the logon user ID and password parameters for the USER subcommand should be provided. This is different when operating FTP interactively online. When FTP is run interactively online, and then the client will automatically initiate a USER subcommand and prompt you for a logon ID. There is no automatic USER subcommand when running FTP in batch mode.
0005
Transfer ASCII data (will be converted on the system to/from EBCDIC).
0006
CL command to be run on the client system to delete the file. (You could instead use the REPLACE parameter with the next statement, the get.)
0007
Retrieve file from RISC System/6000 system.
0008
Close control connection to RISC System/6000 SYSNAMRS.
0009
Open connection to VAX MVAX.
0010
USER subcommand with user ID and password for MVAX.
0011
Retrieve file from VAX replacing existing IBM® i file.
0012
Close control connection to VAX MVAX.
0013
Open control connection to remote system SYSNAM02.
0014
USER subcommand with user ID and password for SYSNAM02.
0015
Transfer EBCDIC data (as it is from a IBM i platform to a IBM i platform).
0016
Send IBM i files to system SYSNAM02 with TCP/IP.
0017
Send this file from system SYSNAM03 to remote system SYSNAM14 through TCP/IP network.
0018
Close control connection to system SYSNAM02.
0019
End FTP application.
