         In response to several requests, I am posting some code in Fortran
         to parse ranges in a fashion similar to the Authorize does it:

         This routine sets bits in a mask depending on whether the
         respective hour is supposed to be prime.

! Abstract:
!
!	This routine will set any designated hour or day as prime or nonprime.
!	 The command looks like Set /[No]Prime Day[=(1,12-14,23)] or similar.
!	 If the list of hours is not there, the whole day is set.  Midnight is
!	 hour 0 and 11:00 pm is hour 23, just like military time.
