Using Chain we can set the pointer to the particular record
according the criteria specified in the chain operation. But
in this case, if the record is found then the pointer will
be set, otherwise i.e., if the record does not exist then
the pointer will not set. This is the reason why we check
with the %Found keyword. And moreover after reading the
record (in case if the record found and there are more
number of records with the same keyword), we can not move
to the another record, which meets the same criteria
specified in the Chain operation. So the conclusion is we
can not read more number of records with the Chain
operation, if there are more number of records exist with
the same criteria in the file.
Where as using READE, we can read all the records which meet
the same criteria using subsequent READE operation. If there
are no records with the specified criteria then the pointer
will be set to EOF.

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.
