Modulation of program flow

Hi all,
I am a new user of VP and like to know where I can found examples how program flow is modulated in UML.
A program call procedures which call procedures and functions with parameters and returns results.
Is there a possibility to modulate this in UML? Maybe with action diagram?
Or is UML the wrong approach?
If possible give me a info where I find examples.

Thanks

Hi khw,

Thank you for your inquiry. Depending on the level of detail you need to model, I suggest you try with Sequence Diagram and Activity Diagram. The following article shows you more details and some examples.
