Answer Posted / vj
1. Find the greatest RRN of the file
2. Have 2 numeric counters.
3. Initialize counter1 to 1
4. Initialize counter2 to the max RRN
5. Chain with counter1 and read the record
6. Chain with Counter2 and read the record
7. Increment counter1
8. Decrement Counter2
9. Repeat Steps 5 to 8 in loop unitl counter 1 = Counter 2
(when counter 1=counter 2) we would have reached the middle of the file

Q:Hi all,i want accurate answer with code using in built functions.please sent me code as soon as posible. I have program nmed PGM1 which '' RETRIEVE Current production date''should correctly default the production date for the user who is issuing raw materials to the manufacturing.The production date can be different from the celendra date. However, the program does not make the correct adjustment for all manufacturing plants. there is a parameter which determines the production start time e.g. 07:00 if the system time precedes this,the program subtracts one from the celendra day.This work fine when the celendar day starts after production day as it does in England,the system should be adding one to the celendar day during the overlap. unfortunately the program was desined to assumed the celendar day always starts before the production day. Change required in the program: Change the PROGRAM PGM1 to use the new parrameter to decide whether to add or subtract 1 from the celendar day when determining the production date.
