Using and Porting GNU Fortran

8.11.9.107 Flush Intrinsic

CALL Flush(Unit)

Unit: INTEGER; OPTIONAL; scalar; INTENT(IN).

Intrinsic groups: unix.

Description:

Flushes Fortran unit(s) currently open for output. Without the optional argument, all such units are flushed, otherwise just the unit specified by Unit.

Some non-GNU implementations of Fortran provide this intrinsic as a library procedure that might or might not support the (optional) Unit argument.
