[fpc-pascal]char 0 in ansistrings

I'm afraid my question was unclear.  Unfortunately, I asked two 
questions with opposite senses, and I don't know which one you 
answered.  Please clarify which of my interpretations of your answer 
is what you intended:

(1) It is ONLY absolutely safe to include chr(0)....IF you typecast 
your ansistring to a pchar, and thus IF you treat it as an ansistring 
WITHOUT the typecast to pchar, it is NOT safe.

(2) It IS absolutely safe to include chr(0), UNLESS you typecast it 
to pchar...because typcasting to pchar is an INSTANCE  (per my 2nd 
question) where it will cause different behavior...

Gimme a (1) or a (2).  Thanks.
