! Note that Fortran 2008 (Section 10.11.3.6) requires that there is
! a value separator between the value and the "!". Thus, all examples
! in this file are invalid; they should either be accepted as vendor
! extension or lead to a run-time error (iostat /=0).
!
! For the c1 and c2 character example, please note that the Fortran
! standard (F2008, 10.11.3.3) requires delimiters; accepting
! a single word (in spirit of list-directed I/O) would be possible
! as vendor extension. But the current run-time failure is fine as well.
!
! Note: After fixing this, warning or error is given with -pedantic -std=xxx
