Re: A82: Re:

Well, not exactly.  First of all, cout is a C++ command.  It is doing much
more than printing "Hello" or whatever to the screen.  It is putting that
data into a stream, which is sent to standard out, or the screen (more or
less).  Writing a C++ compiler for the calc would not be the greatest idea,
since C++ is designed to make large applications easier to write and reuse
code, not write small games.

If you do write a standard C compiler, you would most likely use printf.  You
would take

printf("Hello, World");

and turn it into

    LD HL, (PROGRAM_ADDR)
    LD DE, STRING1
    ADD HL, DE
    CALL PRINTF

STRING1:
    .DB "Hello, World!", 0


This is a basic idea of what the compiler would do.  You would have to
rewrite the printf function to call the rom function to write to the screen.
 I hope this helps.

 so I make it to where the libs turn   cout << "Hello"; to db. "Hello",0
