I'd like to hear what others think about a curious issue I stumbled
across. What should the value of YESNO be in the following cases:
A. open(unit=1,file='junk',form='formatted')
inquire(1,unformatted=yesno)
B. open(1,file='junk',form='unformatted')
inquire(1,formatted=yesno)
For some Fortran compilers under Linux I get the following results:
G95 GFORTRAN Intel Pathscale PGI Lahey NAG
---------------------------------------------------------
A YES YES NO NO NO NO UNKNOWN
B YES YES NO NO NO NO NO
I've taken a look at the standard (9.4.5, 9.9.1.12) and I'm
not sure how to interpret what is meant by the "set of allowable
forms for a file". All compilers but g95/gfortran appear to
interpret it as the allowable forms for the file as it is currently
connected; indeed, form is not one of the changeable modes (9.4.1).
Whereas g95/gfortran seem to interpret it as the allowable forms
for the file in principle, ignoring any connection status.
Thoughts?
