c     SUBROUTINE ctrl_init
c     ==================================================================
c
c     o Set parts of the vector of control variables and initialize the
c       rest to zero.
c
c       The vector of control variables is initialized here. The
c       temperature and salinity contributions are read from file.
c       Subsequently, the latter are dimensionalized and the tile
c       edges are updated.
c
c     started: Christian Eckert eckert@mit.edu 30-Jun-1999
c
c     changed: Christian Eckert eckert@mit.edu 23-Feb-2000
c              - Restructured the code in order to create a package
c                for the MITgcmUV.
c
c              Patrick Heimbach heimbach@mit.edu 30-May-2000
c              - diffsec was falsely declared.
c
c              Patrick Heimbach heimbach@mit.edu 06-Jun-2000
c              - Transferred some filename declarations
c                from ctrl_pack/ctrl_unpack to here
c              - Transferred mask-per-tile to here
c              - computation of control vector length here
c
c              Patrick Heimbach heimbach@mit.edu 16-Jun-2000
c              - Added call to ctrl_pack
c              - Alternatively: transfer writing of scale files to
c                ctrl_unpack
c
c              Dimitris Menemenlis menemenlis@mit.edu 7-Mar-2003
c              - To be consistent with usage in ctrl_getrec.F,
c                startrec and endrec need to be referenced to
c                model time = 0, not to startTime.
c                Also "- modelstep" -> "+ modelstep/2":
c old:      startrec = int((modelstart - diffsecs)/
c old:   &                 xx_???period) + 1
c old:      endrec = int((modelend   - diffsecs - modelstep)/
c old:   &                 xx_???period) + 2
