Actually, implementing this would be a bit harder
than I thought.
It seems that the variable expression is evaluated
at runtime, so you can do things like
$ cat v-fmt2.f
program main
character*1 c
10 continue
read(fmt=9000,unit=*,end=20) j,c
print *,c
goto 10
20 continue
9000 format(i1,t<j>,a1)
end
$ ifort -traceback v-fmt2.f
$ ./a.out
1abcd
1
2abcd
a
3abcd
b
Still doable with non-advancing I/O and internal writes, but
tricky.
