[MITgcm-support] MDSIO

[Ganesh Gopalakrishnan]

Hi Matt,
The fname looks fine, like it starts with 'maskCtrlC'

I made the following changes in mdsio_gl.F and mdsio_gl_slice.F (for
both  3D,2D MDS read fields)

-----------------------------------------(same as old code)
C Assume nothing
      globalFile = .FALSE.
      fileIsOpen = .FALSE.
      IL=ILNBLNK( fName )
CMM(
      pIL = ILNBLNK( mdsioLocalDir )
CMM)


------------------------------------
C Assign special directory
      if ( pIL.EQ.0 ) then
       pfName= fName
      else
       write(pfName,'(2a)') mdsioLocalDir(1:pIL), fName(1:IL)
      endif
      pIL=ILNBLNK( pfName )
--------------------------------------
C If we are reading from a tiled MDS file then we open each one here
        if (.NOT. globalFile) then
         iG=bi+(ip-1)*nsx ! Kludge until unstructered tiles
         jG=bj+(jp-1)*nsy ! Kludge until unstructered tiles
         write(dataFname,'(2a,i3.3,a,i3.3,a)')
     &              pfName(1:pIL),'.',iG,'.',jG,'.data'
         inquire( file=dataFname, exist=exst )
C Of course, we only open the file if the tile is "active"
C (This is a place-holder for the active/passive mechanism
         if (exst) then
          if ( debugLevel .GE. debLevA ) then
           write(msgbuf,'(a,a)')
     &      ' MDSREADFIELD_GL: opening file: ',dataFName(1:pIL+13)
           call print_message( msgbuf, standardmessageunit,
     &                        SQUEEZE_RIGHT , mythid)
          endif
          length_of_rec=MDS_RECLEN( filePrec, sNx, mythid )
          open( dUnit, file=dataFName, status='old',
     &        access='direct', recl=length_of_rec )
          fileIsOpen=.TRUE.
CGG(
C         else
C          fileIsOpen=.FALSE.
C          write(msgbuf,'(a,a)')
C     &      ' MDSREADFIELD_GL: filename: ',dataFName(1:pIL+13)
C          call print_message( msgbuf, standardmessageunit,
C     &                        SQUEEZE_RIGHT , mythid)
C          call print_error( msgbuf, mythid )
C          write(msgbuf,'(a)')
C     &      ' MDSREADFIELD_GL: File does not exist'
C          call print_message( msgbuf, standardmessageunit,
C     &                        SQUEEZE_RIGHT , mythid)
C          call print_error( msgbuf, mythid )
C          stop 'ABNORMAL END: S/R MDSREADFIELD_GL'
CGG)
         endif
        endif 

--------------------------------------

with these changes I was able to pack.
But when reading using optim_readdata.f for linesearch, it fails at the
header check
--------------------------------
ce    Add some more checks. ...

      if (.NOT. lheaderonly) then
c--   Read the data.
-------------------------------

Thanks
Ganesh
