Generating LOAD statements

During the Unload utility process, you can automatically generate LOAD statements to a defined SYSCNTL or SYSPUNCH DD card when you specify certain values for the FORMAT option. The UNLOAD keyword uses SYSCNTL as the default DD name. The UNLD keyword uses SYSPUNCH as the default DD name. You can then use the resulting statement to reload data in another job.

The following table lists format specifications which allow Unload to generate LOAD statements in a SYSCNTL or SYSPUNCH DD:

To statically allocate the data set

You can provide a data set name to the DD statement. 

To override the SYSCNTL DD name default, use the CNTLDDN keyword in the UNLOAD command.

To override the SYSPUNCH DD name default, use the STMTDDN keyword on the UNLD command.

For more information see, SYSCNTL and SYSPUNCH DD statements.

To dynamically allocate the data set

Instead of providing a data set name with the DD statement, you can dynamically allocate the data set by using one of the following methods. If you dynamically allocate the data set, the value of the OVERRIDEOUTPUT parameter determines the method that BMC AMI Unload uses.

• Provide the data set name in the XULDDYNM-unload-data-set-and-discards-automation-control-point.

• Provide the data set name in an OUTPUT-command-for-BMC-AMI-Unload in your unload SYSIN.

  You must place the OUTPUT command before the UNLOAD statement in your SYSIN.

If SYSCNTL, SYSPUNCH, or an alternative DD is not allocated, BMC AMI Unload assumes that you want to bypass generation of the LOAD statement and does not issue an error message.
