  ## Class Name WSCindexData ## Specification of methods ### WSCindexData Function Description Form WSCindexData() Function Constructor of an indexed list data structure. Create an instance of indexed list data. Description Parameters None. Return value A pointer to an instance of an indexed list data Notice Samples
         WSCindexData  indexdata;
         long data1 = 100;
         long data2 = 200;

         //Memorize values by attaching the index
         indexdata["data1"] = (void*)data1;
         indexdata["data2"] = (void*)data2;

         //When you want to do the same using setData():
         indexdata.setData("data1",(void*)data1);
         indexdata.setData("data2",(void*)data2);

         //Obtain memorized data specifying the index
         void* val1 = indexdata["data1"];
         void* val2 = indexdata["data2"];

         //When you want to do the same using getData():
         void* val3 = indexdata.getData("data1");
         void* val4 = indexdata.getData("data2");

         //To obtain the index:
         char* index1 = indexdata.getIndex(0); //"data1" is returned
         char* index2 = indexdata.getIndex(1); //"data2" is returned

         //Obtaining by a position:
         void* val5 = indexdata.getData(0);
         void* val6 = indexdata.getData(1);

         //Obtaining the number of element:
         long num = indexdata.getNum();

         //Deleting data specifying the index
         indexdata.del("data2");

         //Deleting data specifying a position
         indexdata.delPos(0);

         //When you want to clear all data at once:
         indexdata.clear();
