As described in the table below, the Job script parameters you can define in the setSettings {} function of this component are all optional. If you want to keep all the default settings of this component, simply leave an empty setSettings {} function.

Function/parameter	Description	Mandatory?
FORLOOP	Set this parameter to `true` to define a FOR loop: The task will be carried out for the defined number of iterations. By default, this parameter is set to `true`. Set it to `false` if you want to define a WHILE loop. This parameter and `WHILELOOP` are mutually exclusive.	No
WHILELOOP	Set this parameter to `true` to define a WHILE loop: The task will be carried out until a certain condition is met. By default, this parameter is set to `false`. This parameter and `FORLOOP` are mutually exclusive.	No
FROM	Use this parameter to specify the first instance number from which the loop should start. For example, a start instance number of `2` with a step of `2` means the loop takes on every even number instance. The default value is `1`. This parameter works only when the `FOR` parameter is set to `true`.	No
TO	Use this parameter to specify the last instance number with which the loop should finish. The default value is `10`. This parameter works only when the `FOR` parameter is set to `true`.	No
STEP	Use this parameter to specify the step of instance number increment or decrement. For example, a step of `2` means every second instance. The default value is `1`. This parameter works only when the `FOR` parameter is set to `true`.	No
INCREASE	Set this parameter to: `true` to allow only an increasing sequence. `false` to allow only a decreasing sequence. By default, this parameter is set to `true`. This parameter works only when the `FOR` parameter is set to `true`.	No
DECLARATION	Use this parameter to specify an expression to initiate the loop. The default value is `int i=0`. This parameter works only when the `WHILE` parameter is set to `true`.	No
CONDITION	Use this parameter to specify the condition for the loop to run. The default value is `i<10`, which means the loop runs until the `i` value reaches 10. This parameter works only when the `WHILE` parameter is set to `true`.	No
ITERATION	Use this parameter to define the operation to be performed upon each iteration. The default value is `i++`. This parameter works only when the `WHILE` parameter is set to `true`.	No
TSTATCATCHER_STATS	Set this parameter to `true` to gather the processing metadata at the Job level as well as at each component level. By default, this parameter is set to `false`.	No
LABEL	Use this parameter to specify a text label for the component.	No
