"1. It returns a reference to the following variable". I read the reference and understand; now I need to think of what it means in the program.

"2. They operate on the array referenced by the scalar". Again read your reference and have concluded I need to read more about the use of references.

"3. After the first call returns". In thinking about this I believe what is happening is like "nesting". I have been going through this using a single IP range and printing to try to understand. After reading more on the use of references will continue that effort.

Thanks, will likely be back
