Converting pl/sql structure (record) to a string

Question

I need to convert a structure to a string, does anyone know how to do this?
e.g.
TYPE Msg IS RECORD /* record to store message info */
record_type VARCHAR2(3),
field1 VARCHAR2(10),
my_dept_nbr dept.dept_nbr%TYPE);
My_Msg Msg;
My_Msg.record_type := 'ABC';
My_Msg.field1 := 'whatever';
My_Msg.my_dept_nbr := 13;
Now I want to assign My_Msg to a string!!!

Answer 1

Not really.
I wanr to define a series of structures in a common package spec and use the definitions in other packages that will populated them, some of these messages can be complex and large.
I then need to pass the messages as a string vis MQ to another applications.
I would like to perform an assignment such as:
My_String := My_Msg;
or My_String := to_char(My_Msg);
or My_string := fncStructureToString(My_Msg);
