What is the difference between data flow and process flow in a script?

Question

I am creating a script, what is the flow? What is the difference between data flow and process flow in scripts?

Answer

Scripts have "process flow," which represents the flow of processing, and "data flow," which represents the flow of data.
Process flow and data flow are collectively called "flow".
In HULFT Square, by separating process flow and data flow, the result of processing once can be used many times in subsequent components.

Process Flow

-Process flow is a flow of processing.
-Scripts are processed in the order in which they are linked by process flow.
-A process flow starts with a "start" component and ends with an "end" component and a "break" component.
-Process Flow is indicated by a solid black line.

Data Flow

-Data flow refers to the flow of data.
-Data flow can be drawn from a read system connector or converter to a write system connector or converter.
-Data flow is indicated by a yellow line.
