i5/OS native system files have a fixed record length. Although you can select a record format of
Fixed
and specify the record size, it is simpler to select a record format of
Default
.
i5/OS has limited support for variable file types. Only files in the i5/OS integrated file system (IFS) can use UNIX-like variable-length records.
i5/OS files are typically partitioned. File names are expressed in terms of
library
/
filename
(
member
). You can omit the member component when the file has only a single member. Otherwise, the member component must either specify the exact member name or be set to an operating system keyword such as *ALL, *FIRST, or *LAST.
The maximum record size that i5/OS can process is 32,768 bytes (32 KB).
