Re: closing unit=5 and unit=6 and print *

Hello,

See INPUT_UNIT, OUTPUT_UNIT, ERROR_UNIT in ISO_FORTRAN_ENV.

It is convenient to have a subroutine that can write to a file or print

less convenient to wrap IF statements around all WRITE statements to
choose between unit=* and unit=some_number. If a code assumes that 6 is
the unit for standard output, a PARAMETER should be declared and used
for this, to make this assumption clear.

Yes, but isn't that included in Fortran 2003? (I do not have the
standard
near me, so I can not check, but I remember something like that).
Otherwise, I think it is one of the things Dan Nagle's portability
project takes care of.

Regards,

Arjen
