Phil,

Thank you, but how?
The HP Broadband Systems (HPBS) only recognizes ANSI C and TTCN 
(Tree & Tabular Combined Notation) object codes.
Our clients want us to integrate their Ada95 OO code with our C codes 
which is almost impossible IMHO because C is not an OO language.
How do we convert Ada's _package_, TEXT_IO, .... to HP's C function?
The HPBS is a validation device for us to emulate our clients'
SDH/SONNET/ATM networks.

My idea is, 

Ada95_to_ANSIC 
BEGIN
        IF case I := Ada to C conversion not gonna to work;
                THEN we have recode our client's OO Ada code to C;

        ELSE case II := there is an Ada to C convertor;
                THEN we let the converter to fix the conversion problem;
END
  
OK, another question. 
How do you use C to code like an OO Ada program?
Thank you in advance.
