Hi, I'm in the process of converting a few thousand lines
of Turbo Pascal code to c using the P2C translator with
the emx/gcc as the target compiler. Much of the code compiles
fine, but in the process of linking (I think!), I get errors
saying that functions like gotoxy, readkey, etc., are not defined.

I'm linking to libp2c.a and expected these functions to be
implemented in this library. Are these functions not available
in this translation package? Do I have to go in and change these
functions to their c equivalent?

If anyone can give me a hint about how to do this, I'd
truly appreciate it. I just don't want to start replacing
them by hand and then find that there was some problem with
the way I'm doing things and that I've wasted precious time.

Thanks very much for any help -- alann

Below is an Turbo Pascal example, the translated code
and the error messages from the compiler/linker:

gotoxy(10,20);
writeln("Hello World");

End.
