EXAMPLE OF USING A LIST DATA TYPE

List can be used to store a list of elements and this type is quite portable for quick manipulation.

You can either use ListEnumerator or ListIterator. These 2 classes are quite similar unless must use ListIterator if you want to delete an element in the list.

static void STU_List(Args _args)
{
    List            lst;       //list
    ListEnumerator  lstEnum;   //traverse through the elements in the list
    CustTable       custTable;
    VendTable       vendTable;
    Common          common;
    int             i;
    ;
    lst            = new List(Types::Record);
    lstEnum    = lst.getEnumerator();

    lst.addEnd(CustTable::find("4000"));
    lst.addEnd(VendTable::find("3000"));
    lst.addStart(CustTable::find("4020"));

    info(lst.toString());
    info(lst.definitionString());
    info(lstEnum.toString());
    info(lstEnum.definitionString());

    lstEnum.reset();
    lstEnum.moveNext();        //must move next to get to the first

    for(i=0; i<3; i++){
        common          = lstEnum.current();
        if(common.TableId==tablenum(CustTable)){
            custTable   = lstEnum.current();
            info(strFmt("%1, %2", custTable.AccountNum, custTable.Name));
        }else if (common.TableId==tablenum(VendTable)){
            vendTable   = lstEnum.current();
            info(strFmt("%1, %2", vendTable.AccountNum, vendTable.Name));
        }
        lstEnum.moveNext();
    }
}
