It will be used as a subscript to move the FROM-CITY-NAME from this table. MOVE FROM-CITY-NAME (FROM-CITY).. TO-CITY on the input has values of 1, 2, 3, 4 or 5. It will be used as a subscript to move the TO- CITY-NAME from this table. MOVE TO-CITY-NAME (TO-CITY)... You can see that there are three 05s that describe the 3 places you can fly from. In this example consider these the rows. Under the redefines, I am redefining these as 05 FROM-CITIES. Under each of the 05s, I have put five 10 levels to describe each of the cities I can fly to. In this example, consider them columns. On the redefines, these are called FARE with an occurs of 5 times. Looking at it, I have three 05s redefined as 05 occurs 3 times and under each 05 in the original table I have five 10s redefined as 10 FARE with a picture and occurs 5 times.
