Looping Execution for Streams

Using the Execution tab in the stream properties dialog box, you can set up looping conditions to automate repetitive tasks in the current stream.

Once you set these conditions you can use it as an introduction to scripting as it populates the script window with basic scripting for your stream which you can then modify - perhaps to use as a base from which to build better scripts. See the topic Global Functions for more information.

To set Looping for a Stream

1. On the File menu, click Stream Properties (or select the stream from the Streams tab in the managers pane, right-click and then click Stream Properties on the pop-up menu).
2. Click the Execution tab.
3. Select the Looping / Conditional Execution execution mode.
4. Click the Looping tab.

Alternatively, on the Tools menu, click:

Stream Properties > Execution

As a further alternative, right click on the node and from the context menu, click:

Looping / Conditional Execution > Edit Looping Settings

Iteration. You cannot edit this row number value, but you can add, delete, or move an iteration up or down using the buttons to the right of the table.

Table headers. These reflect the iteration key and any iteration variables you created when setting up the loop.
