Status code 92 when accessing VSAM file dynamically

This is the code for reading and extracting data A3 file. This file has multiple occurences of account numbers but the code is not reading all occurences and gives file status 92. After that if I try to read data from the file it gives status code 46. I am not able to figure out what is the problem.

Thanks in advance.

You posted a lot of garbage without really telling us much.

Are you attempting to read an alternate index?
What is the file status code after the START?
Why would you attempt to read after getting a 92 -- the 46 says a sequential READ was attempted but no valid next record has been established (which implies that your START may not be working, or that you got a file status 92 on a prior read)?
Did you define the extended file status code for the VSAM file?
Why does your code not use the file status code since it is obviously available from your post title?

And a terminology note -- your post title says you're "accessing VSAM file dynamically". This is wrong -- you may indicate that access is dynamic to COBOL, but every READ is a random read and every READ NEXT is a sequential read, period. You cannot do anything but read randomly or sequentially -- COBOL doesn't support dynamic reads. The specific method you are using is skip sequential processing -- START to establish the location, then sequential READs of the records.

I am not trying to read alternate index. Actually before posting I have removed the display that might have removeed the status code of file. I didn't try checking file status codes after START. The problem is I am not able to understand why its throwing status code 92. According to the code it should read until the key changes and read the next key after that but its throwing status code 92 after it reads all occurences of first key.

It is not "throwing" anything - it is "issuing" or "giving". "Throw/throwing" are not mainframe terms.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

According to the code it should read until the key changes and read the next key after that
This is NOT how COBOL works. When you do the START, you established the logical record sequence. When COBOL reads a record that does not match the key you specified, you will get either the AT END processing (if specified) or file status 10 (end of sequence or file). If you then attempt to read another record after getting the file status 10, you WILL get a file status 92 because you're attempting to read after end.

And I reiterate what you have been told: COBOL and the mainframe do not EVER, under any circumstances "throw" things. Mainframes in the system z series (and its predecessors) have been around for more than 50 years at this point. There is long-established terminology for mainframe events and processes, and attempting to use non-mainframe terms (such as "throw") with the mainframe shows that you are not ready to participate in mainframe fora. Learn the correct terms (many of which have been around for most or all of the 50+ years the mainframe has been around) and use them.

Thanks for letting me know the terms. I was not aware of that as I am at a beginner level. Also for providing me the details of the reason of statis code 92.
