Here's a small trick to make it easier to define tokens and their corresponding
strings. See Steve Oualline, Practical C++ Programming, O'Reilly and Associates, Inc., 1995. pp460-461.

//----------------------------------------------------------------------------
//  Using the define trick to generate tokens and their strings
//----------------------------------------------------------------------------

#define _TOK T(_tik),T(_tak),T(_tok),T(_toe)

#define T(X) X
enum TOKTYPE { _TOK };

#undef T
#define T(X) #X
char TOKSTR[4][20]={ _TOK };


// The above is equivalent to

enum TOKTYPE { _tik, _tak, _tok, _toe };

char TOKSTR[4][20]={"_tik", "_tak", "_tok", "_toe" };
