From 9i DOC:
Suppose a subprogram declares an IN
parameter, an OUT parameter, and an IN OUT parameter. When you call
the subprogram, the IN parameter is passed by reference. That is, a pointer to
the IN actual
parameter is passed to the corresponding formal parameter. So,
both parameters reference the same memory location, which holds the value of the
actual parameter.

Bear in
mind that you cannot declare a procedure like this:
procedure blah(
p in varchar2(200)
);
it has to be:
procedure
blah(
p
in varchar2
);
So even though a
declaration like Rob's
test.col_01%type
appears to tell
Oracle that the parameter
is limited to 200 bytes I believe there is
no
limit, other than the inherent limit of varchar2(),
viz:
4,000.

|Initially is will be nothing unless test.col2 has a default
value as
|varchar2 structures are data_length followrd by actual string.
The
maximum
|that p_in_one can have is 200 bytes thought due to its
anchored
definition.
|
|The answer, none initially as it will be
initializes to NULl value,
then
|whatever you assign ti it plus 2 bytes to
store the length of the
actual
|string, max size is 200+2 bytes (assuming
standard characterset).
|
|This has no baring on max size of varchar2
because by definition of
|p_in-one, its max length is limited to
200.
