scripting: getting the whole property list of an object

["Frank Lenhard" <frank.lenhard(at)gmail.com>]

i am sorry if this is totally obvious and beginners stuff (that what i am anyhow to scripting) but:

how can logmessage all properties that exist on a object, so i can change them later using the object model?
i need the syntax to access stuff like visibility, position, null shapes etc. 
i find some stuff for dedicated objects like nulls and others, but in general i would like to select a object and get a list with all available properties.


thanks a lot
ciao
