I do not call it an object, to me its just a variable.  Anything beyond that 
(an object wich might contain other properties as well as methods) is (way) 
outside of my scope.

Indeed.  But if there is one thing I've learned from Usenet it is that you 
need to keep the context to a question simple.  Referring to all the other 
adresses and what they point to would just be "muddying the water".

Agreed.

But thats the crux : somethimes I get the distinct feeling that someone is 
talking about the address (pointing to a string or otherwise), but than 
suddenly seems to talk about the variable holding it.  :-\

I think I can translate "pointer value" as to be meaning an address.  For 
the others ? I do not have the foggiest I'm afraid.

Whoooo....  Is that *on*, of *off* topic ?  Not that it matters much which 
one though. :-)

AFAIK most people do not use that phrase but use the (shorthand) "string 
pointer" (with or without the space) instead.  But yes, I would also.

Though thats the whole problem to me : most people seem to use that "string 
pointer" phrase for the addres (the "value of pointer type") *as well as* 
the variable (or worse : an object) its stored in.


But I think I am going to stop asking.  It looks like the destinction 
between the address and what its stored in isn't of much, if any, importance 
to the people here.

Oh well, you can't get /everything/ answered. :-)
