The WRITE FILE MARKS command causes a sequence of file marks to be written
at the current logical position. The number of file marks to be written is indicated in
the Count field. If the Immed flag is set, status is returned immediately, before the
file marks are written to tape. If the Immed flag is clear, the file marks and any
buffered data is written to tape before status is returned.
If the Immed flag is clear and the Count field is 0, then all buffered data is flushed
to tape before the command is reported.
If the current logical block number is greater than FFFFFF00h and less than
FFFFFFF0h, rules for Logical EOM processing are applied. If the current logical
block number is FFFFFFF0h, rules for physical end of tape processing are applied.
