enum eValType { UNDEF, INT_VAL, REAL_VAL, STRING_VAL, ARRAY_VAL, HASH_VAL, POINTER_VAL};

Функция приведения enum к human-readable виду:

...
switch(eType)
{
	case UNDEF:       return "*UNDEF*";
	case INT_VAL:     return "INTEGER";
	case REAL_VAL:    return "REAL";
	case STRING_VAL:  return "STRING";
	case ARRAY_VAL:   return "ARRAY";
	case HASH_VAL:    return "HASH";
	case POINTER_VAL: return "POINTER";
	default:          return "OMG_WTF?!";
}
