//  ---------
// Zero-pointer for use in ellipsed (...) parameter lists which expect a
//   pointer which may have another size than an int.
// 	 Must be a define to be used in precompiled headers:
#define NIL   ((void*)0)
// char '\0'
#define NULCH '\0'



// Boolesche Operatoren
#define AND &&
#define OR  ||
#define NOT !

// Macro for distinguishing dynamic allocated pointers from
//   referencing pointers
#define DYN		// Exact specification: DYN has to be used if and only if:
				//	1. DYN specifies a class member pointer or reference variable and
				//     the class must free the referenced memory.
				//  2. DYN specifies a pointer or reference (return-) parameter of a function
				//     and for in-parameters the function or its class
				//     must free the referenced memory, the parameter is then called
				//     a let-parameter.
				//     For out- and inout-parameters
				//	   or return values the caller of the function hast to
				//     free the referenced memory.
				//
				//     It is irrelevant who allocated the memory!
				//
				//     DYN - variables use the prefixes "dp" or "dr" instead of "p" or "r".

/* Additional Programming Conventions
1. see above at "#define DYN"
2. function parameters get one of these prefixes:
	- i_	 := Function uses only the value, but must not change a referenced variable.
	- o_	 := Parameter is undefined until function has set it.
				Parametere must be set by the function.
	- io_	 := Function may use and change the referenced variable.
	- let_	 := Funktion may use and change the referenced variable and HAS TO free the
				associated memory.
3. Global constants get the prefix 'C_', global variables the prefix
   'G_', local constants the prefix 'c_' .
4. Static members end with an underscore '_'.
