Thanks Joe for that. Interestingly, I have to specify an attribute(either
length or format) before the call missing routine, otherwise, the log
says: The MISSING subroutine call does not have enough arguments.
Even in specifying the attributes, I can't just use:

           format _a: 3.; /* I need to list all variables explicitly, which
I don't want to manually do */
           call missing(of _a:);

Any other ways?
