result)

Declare a Function or a procedure as
    MyProc(P1: String; Args: Array of Const);

And as Michael Van Canneyt said, you can use as many parameters. But dont
forget to compile it with -S2 option.

Like C, you must provide some method to distinguish between different data
types within the first parameter itself, and access the rest using:
    Args[ParameterNumber].vChar for Char
    Args[ParameterNumber].vString for string and
    Args[ParameterNumber].vInteger for integer data types.
