It's hard to produce a manual for DBP really, it's like writing a manual for "English" or "Spanish". It is a language to write programs in not a "Game maker".
You will find the help files are a bit like a cross between a dictionary and a phrase book for that very reason.
You will find a definition of what each command does and an example of how it might be used. They are not always perfect (or accurate) but everyone here on the forums will try to help you when you get stuck
If you persist in communicating by smiley though you might need to write your own 'manual'...
