The FILE STATUS clause of the FILE-CONTROL paragraph allows
for each file to be associated with a file status key (i.e.,
the 2-character data item specified in the FILE STATUS
clause). If the FILE STATUS clause is specified for a given
file, a value indicating the status of each I/O operation
against that file is placed in the associated file status
key. This value is stored in the file status key as soon as
the I/O operation is completed (and before execution of any
EXCEPTION/ERROR declarative or INVALIDKEY/AT END phrase
associated with the I/O request).

Note: This element may behave differently when the CMPR2
compiler option is used. The file status key is divided

into two status keys: the first character is known as file
status key 1; the second character is file status key 2.
