In this use case, a three-component Job uses several DqStringHandling functions concurrently to handle several given strings.

![Screenshot of the Job in the design workspace.](https://help.qlik.com/talend/en-US/studio-user-guide/Resources/images/DQ_Routine_String1.png)

In this Job, the three components are:

* tFixedFlowInput: this component provides the strings to be handled by the DqStringHandling routines you select.
* tMap: this component transforms the given strings using the DqStringHandling routines you select.
* tLogRow: this component displays the execution result of this Job.

To replicate this use case, proceed as follows:

From the result, you can see that the contains\_only\_initials row outputs false because there is a space in front of U.S.A. while the contains\_only\_initials\_after\_trim presents true because this space is trimmed; the safe\_trim row presents U.S.A. with the space trimmed and the safe\_concat row outputs U.S.A.
