SYSTEM-COMMAND

Common Fields for all Operating Systems

Additional Fields Supported for z/OS

Field Descriptions

Output line. If more than one output line is expected, a FIND loop is required to retrieve all of them.

For COMMAND FTP, commands specific to FTP are set up in field SUB-COMMAND. Up to 50 SUB-COMMANDS are allowed. SUB-COMMANDS are only allowed for ONE COMMAND in a FIND or PROCESS statement.

As an example see section How to run an FTP from Mainframe Natural Using Entire System Server. Using the new sub-command key PASSWORD will prevent the password to appear unencrypted, e.g. in traces or outputs.

Relevant Error Codes

Example:

z/OS: The following program issues the TSO command LIST and requests a list of all datasets that start with the string WKK:

FIND     COMMAND WITH  COMMAND = 'LISTC LVL (''WKK'')'
  DISPLAY LINE (AL=79)
  END

How to run an FTP from Mainframe Natural Using Entire System Server

Using the view SYSTEM-COMMAND, you may execute an FTP from Natural to anywhere, as shown in the example below. First, ask your TCP/IP administrator for the configuration information required by the TCP/IP client programs. This dataset/member is allocated dynamically with a special DDNAME SYSTCPD. The dataset/member name will of course be different at your installation.

Then, code the command FTP, and the subsequent FTP commands are coded here as SUB-COMMANDS.

In the following example, you logon as an anonymous user to the Software AG FTP server and read a list of directories or files available at this moment.

DEFINE DATA LOCAL
01 SYSTEM-COMMAND  VIEW OF SYSTEM-COMMAND
  02 LINE
END-DEFINE
FIND    SYSTEM-COMMAND  WITH NODE = 148
 AND COMMAND = 'alloc f(systcpd) da(''sysm.daef.parmlib(tcpdata)'') shr'
    AND COMMAND = 'FTP                   '
    AND SUB-COMMAND = 'ftp.softwareag.com'
    AND SUB-COMMAND = 'anonymous'
    AND SUB-COMMAND = 'PASSWORD=abc@softwareag.de'
    AND SUB-COMMAND = 'dir        '
    AND SUB-COMMAND = 'help       '
    AND SUB-COMMAND = 'quit    '
  PRINT  LINE(AL=132)
END-FIND
END  

The output looks like this:
