Hi,

I would like to know what is meant by related and unrelated 
modules??

In the examples provided, include_module and import_module are 
used. They perform almost the same as including other modules from 
different files as sub-modules, except that, import_module helps 
retain the value of variable across child modules.

Plz do reply at the earliest. Thanks in advance.

Regards,

Noel
