DEAR ITS REALLY SIMPLE U SHOULD TRY IT ON YOUR OWN:
SUPPOSE EMPNO FIELD IS KEY FIELD OF FILE HAVING RECORD :10,20,30,40
SO WAT HAPPEN READP READ PREVIOUS RECORD AND SETLL SEARCHING DATA THROUGH KEYFIELD
SO AFTER READING RECORD 20 IT GOES TO 30 BUT WE ARE SEARCHING FOR 25 WHICH IS NOT PRESENT SO IT WILL RETURN 20 AND OUTPUT
MEANS IF FIELD HAVING DATA LIKE : 10,20,24,30,40
THEN IN THIS TIME OUTPUT WILL ME 24 OK BYE T.C

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.
