Repositions an open file to the beginning of the preceding record in that file.
Terminates the connection between a logical unit and a file or device.
Deletes a record from a file.
Writes an end-of-file record to a specified unit. When an input statement reads this record, an end-of-file condition results.
Questions the status of specified properties of a file or logical unit.
Connects a Fortran logical unit to a file or device; declares required attributes for read and write operations.
Repositions an open file to the beginning of that file.
Frees a record (locked by a previous READ statement) to permit further access to the record.
