Creating a user routine

Procedure

In Repository, click the Code node, then Routines, then right-click on Routines and select the Create routine option to create a user routine.
In the pop-up window, enter a routine name in the Name field (this example uses MyRoutineDemo). Then click Finish.
By default an example function called helloExample is provided whenever a new user routine is created, as follows:

Information noteNote: The function annotates are optional, but if you want the function to be displayed in a category so that the function can be chosen from the category when editing the code expression, as the below figure showed, you have to specify the {Category} property.
Create a new function called reverseString that is used to reverse a string.

Information noteNote: If you need to use external JARs in the function, right-click on the routine name in Repository and select the Edit Routine Libraries option to add external JARs.
