13106125972011081701DB1100000

when givem a key/partial key the read should be random first and then sequential as like reading all the bank statements in 6th month.

can any one help me out...

If you OPEN a file, you READ the file. Using the ACCEPT verb means the system is expecting you to provide input in //SYSIN and the file will be completely ignored -- in which case you risk a S0C4 storage abend by referencing storage that does not exist.

In other words, your code is wrong and you need to fix it.

You are doing a START in the paragraph you are performing. You, at best, get START, START, READ, START, READ, START, READ... either in a "loop" or you will eventually do a START which gets EOF and then you do a READ = logic error.

I can't tell which, but whichever your program is wrong.

Check the return code of the start command. If you don't get a clean start, you can't do a read.

I would do something like this in stages.
First, make sure your ACCEPT is working the way you think it should. Comment out the perform and display the "log" variable.
If that's right, then go ahead and do the perform, but comment out the read. Just do the Start and display the status code.
If that's all correct, then add the read back in, but add some code to check THAT status code too.

I also think you're asking for trouble using an ACCEPT statement with that "LOG" variable which is part of the FILE1 definition. You see, when you coded the "SELECT" statement for FILE1, you told COBOL to look to the "DD1" DD statement in the JCL for that data. You also said that is was a VSAM file. Then you used ACCEPT to try and put data into it.

As billy pointed out, you're also doing the start more than once.

thank you guys for your sugestions:):). i then edited the procedure division as follows still i get file status 92. nopt only this program but the cobol file concept programs which were executing correctly are are also throwing file status 92, 23 etc..

PROCEDURE DIVISION.
MAIN-RTN.
OPEN INPUT FILE1.
DISPLAY FS.
ACCEPT LOG.
MOVE '1310612595' TO LOG.
START FILE1 KEY IS >= LOG.
PERFORM UNTIL FLAG = 'N'
READ FILE1 NEXT AT END MOVE 'N' TO FLAG END-READ
DISPLAY BK SPACE FS
END-PERFORM.
CLOSE FILE1.
DISPLAY FS.
STOP RUN.

Is there any data on your file? 23 is end-of-file. 92 you would get if you read after receiving end-of-file. If you have lots of programs getting these, which weren't before, I'd guess you have either an empty file or a file truncated before the keys that you are using (in all the programs... that is why I think the first is most likely).

jophine89, I get the feeling your code is wrong because your approach is wrong. Please -- start at the beginning and tell us what you are attempting to do in plain English without any code involved. If we do not understand, then we'll ask for clarification -- and if we do not understand, then you DEFINITELY do not understand well enough to write code.

It appears to me that you are attempting to read some kind of log file and use each record to retrieve matching data records from a VSAM KSDS file. However, the problems I see at this point are:
1. the VSAM KSDS file is defined with a key and nothing else -- you could easily get a 92 file status if there is more data in each record than your COBOL program shows
2. it appears you are attempting to use one file where you need two files (sequential log file and indexed VSAM file).
3. you define the file status and display it, which is good, but you don't have any code to actually CHECK the file status. If you do the OPEN, and you get anything in the file status cod except 00 or 97, you need to stop your program IMMEDIATELY -- because your starts and reads of the VSAM file will not work, period. Similarly, once you do the START you do not check to see if the file status is good -- and I've seen a lot of START commands return file status codes other than 00.
4. once you do a start on the VSAM file, you just read and display until end-of-file. If you are trying to read a file of log records and display matches in the VSAM file, the last record in the VSAM file will be displayed once for each input log file record -- 15 times based on the sample data in your original post. Why are you doing this?

Why aren't you checking return code after the start? That would tell you a LOT.
