I have two files , file1 is input file it contains
10,20,30,....,records
but i want to display the records in file 2 as reverse order
.how can we do by using jcl& cobol(dont use array)
please any one can tell me the answer
Answer Posted / abhishek
First open file-1 as:
OPEN INPUT FILE-1 REVERSED
->If REVERSED clause is specified at the time of opening a
particular file, then that file can be read in reverse
direction.
Now we can read file-1 like
READ FILE-1
INTO ws-record
NOT AT END
PERFORM PARA-1
END-READ
PARA-1
WRITE FILE-RECORD
FROM WS-RECORD
END-WRITE

I have a program with an Array of 5000 occurences which is being passed from 5 sub levels to the front end screen. Thess 5 programs using each 5*2 = 10 different arrays with size as 5000. This is causing the transaction to utilize more storage consupmtion. I am looking to reduce the storage consumption. As part of that initially i thought Dynamic array may solve my problem. After viewing the comments given i see its same as normal array. IS there any other way we can resolve this issue?
