Sequential file (SEQFIL)

The IBM® i supports access to nonkeyed physical files via the DDM sequential file model.

The support has the following characteristics:

The sequential file can be delete or nondelete capable on an IBM i.
The sequential file on an IBM i can have a fixed-length record (RECFIX) or variable-length record (RECVAR) for storage. Once a non-IBM i source server opens a file on the IBM i target using variable-length record access, the IBM i target continues to send and receive variable-length records on all subsequent I/O operations.
