How to Chain Functions Together
To chain one function to another:
Complex expressions can be built by chaining functions (that is, mapping the output of one function to the input of another). For example, to remove all leading and trailing spaces from the output of the concat function, perform the following steps:
- Drag the left-trim and right-trim functions into the border area of the concat function.
- Chain them as shown in Figure 41-35 by dragging lines from the output side of one function to the input side of the next function.
Chaining can also be performed by dragging and dropping a function onto a connecting link.
