        CustTable c;

        DictTable dt;

        dt=new DictTable(c.TableId);

        n=dt.fieldCnt();



        print "Number of fields in table: ", n;

        for(i=1; i<=n; i++)

        {

            k=dt.fieldCnt2Id(i);

            print "The ", dt.fieldName(k), " field exist with Id=",k ;
