Sequential WRITE statements transfer output data to external sequential access records. The statements can be formatted by using format specifiers (which can use list-directed formatting) or namelist specifiers (for namelist formatting), or they can be unformatted.
A sequential WRITE statement takes one of the following forms:
Unformatted, sequential WRITE statements transfer binary data (without translation) between the entities specified in the I/O list and the current record. Only one record is written.
Objects of intrinsic or derived types can be transferred.
This form of WRITE statement writes exactly one record. If there is no I/O item list, the statement writes one null record.
