The Summary Info report is useful when you think you are nearly finished with your project, because this report tells you a summary of:

1. all the different types of Variables that send data in either direction,
2. all Variables (and "Communication Controls") that send data IN to the PC, and
3. all Variables (and "Communication Controls") that send data OUT from the PC.

Each section of the Summary Info report lists the names of all Variables and Controls that fit the criteria of the section.  For example, one section in the example report below shows the number and names of all Input Integer Variables.
