GFORTRAN_UNBUFFERED_ALL—Do not buffer I/O on all units#
This environment variable controls whether all I/O is unbuffered. If
the first letter is y
, Y
or 1
, all I/O is
unbuffered. This will slow down small sequential reads and writes. If
the first letter is n
, N
or 0
, I/O is buffered.
This is the default.
