subroutine read_namelist(single_column_in, scmlon_in, scmlat_in, nlfilename_in ) 1,119
!-----------------------------------------------------------------------
!
! Purpose:
! Read data from namelist cam_inparm to define the run. Process some of the
! namelist variables to determine history and restart/branch file path
! names. Check input namelist variables for validity and print them
! to standard output.
!
! Method:
! Important Note for running on SUN systems: "implicit automatic (a-z)"
! will not work because namelist data must be static.

! Note that the following interfaces are prototypes proposed by Henderson

! interfaces should be refined via review by other CAM developers.
! Interface *_defaultopts() gets default values from the responsible

! Interface *_setopts() sends values to the responsible module (Expert)

! The cpp SPMD definition provides for the funnelling of all program i/o
