Help with basics

These Parameters are only for the experienced, you can safely ignore them. They reach deep into programming territory.

Just starting out with Girder, and need a little help to get on my way. As I'm not from a programing backround could someone please explain lparam and wparam to me.
I have no problem getting commands to work, I just don't understand what these entries control.
It seems that I can use either the lparam value with a 0 in wparam, or the wparam value with a 0 in lparam and the command will still execute.
Hope that makes sense.
Thanks
