Answer / kb
An OPTIONAL file is being opened as EXTEND or I-O. Optional
files are files that are not necessarily present each time
the program is run. You can define files opened in INPUT,
I-O, or EXTEND mode as optional by using the SELECT OPTIONAL
phrase in the FILE-CONTROL paragraph.

Answer / sandy
OPTIONAL clause can be specified for files opened INPUT,
OUTPUT, I-O and EXTEND modes. It will not give any
compilation error.
If we do not have DD statements for such files during
execution, the following file status code would be obtained
when we open the file.
INPUT (JCL RC = 0)
------
Open statement will give file status of '05'. Open is
successfule but file is not present.
EXTEND (JCL RC = 0)
------
Open statement give file status of '96'. No DDNAME present.
I-O (JCL RC = 0)
------
Open statement give file status of '96'. No DDNAME present.
WRITE (JCL SOC4 ABEND)
