Subroutine reg1st is i/o routine for the user defined horizontal ! and vertical regional masks used in MOM. ! It is also the i/o routine that can be used to write volume ! information for the horizontal regions used in calculating ! volume weighted averages of tracers and surface tracer fluxes. ! Both formatted and unformatted i/o is supported. ! (see "cregin.h" for more details on variables). !======================================================================= implicit none ! nunit = unit to be written to or read from ! wrform= true(false) switch for formatted(unformatted) writes !
