LENGTH={nnnnn | 0}

This parameter defines the maximum logical record length, also called the string length, which is used to encode the data records of the file.

It is good practice to omit this parameter if you are sending or receiving a file into a file that already exists because the platform server will determine the appropriate length. If you are receiving (initiator receive) a file that does not exist, you must indicate the length if you do not want the platform server to use the default value.
