COBRT102 Sequential file with non-integral number of records (Fatal)

You have either specified an incorrect record length for a sequential file, or the sequential file you are trying to access is corrupt in some way, or the file which you have specified is not a sequential file.

Resolution:

Recode your program so that it specifies the correct type of file, or if the error is the result of a corrupt file, try to run the program again using a backup copy of that file.
