I think some more details would be helpful

1) What is the error you are getting?
        Supply all error messages and codes
2) What version of z/OS?
3) What is reading the file?  CICS, IMS, COBOL? Please provide release levels
        Show any file definitions, for example if COBOL provide the IO SECTION.
4) Why did you expand it to 250 if it can only read 200?

If your program/appl does a get for 200 records, but the file is now 250 
records, I would think it would any extra data would be ignored.

Do you use a fixed length when you get the data?  Or do you get data based on 
some other process?

Thanks
