System variables

Enrichment automatically creates variables called system variables. System variables are produced by key Enrichment steps. If a particular step, such as Presort, is not performed, then system variables normally produced by that step will have no value.

You can use system variables just as you would variables you create. System variables can be applied in your control or rule file. Control files and rule files share variables, so when you set a variable to a value in the control file, that variable and its value are available in the rule file.

Note: The value of system variables can change frequently. If a value is assigned to a system variable and later in the code you are expecting that value to still be in the system variable, it may not be because subsequent function calls or section changes could have modified the value.
