--- Comment #1 from G. Steinmetz <gscfq@t-online.de> ---

There are several variants :


$ cat z3.f90
subroutine s
   integer :: a(num_images()) = 1
   print *, a
end


$ cat z4.f90
subroutine s
   integer :: a(this_image()) = 1
   print *, a
end


$ cat z7.f90
subroutine s
   integer :: a(command_argument_count()) = 1
   a = 2
end


$ cat z8.f90
program p
   block
      integer :: a(command_argument_count()) = 1
      print *, a
   end block
end


$ cat za.f90
function f()
   integer :: a(command_argument_count()) = 0
   a = 1
end


$ cat zb.f90
program p
   block
      integer :: n(command_argument_count()) = 0
      n = 1
   end block
end
