4  To apply the changes to the default configuration of MITgcmUV:  The notes for this experiment are now on-line.  Please see the third
5    cd bin  chapter ("Getting started with MITgcm") which is available at:
   ln -s ../verification/exp2/code/SIZE.h ../bin/  
   ln -s ../verification/exp2/code/CPP_OPTIONS.h ../bin/  
   ln -s ../verification/exp2/code/CPP_EEOPTIONS.h ../bin/  
   ln -s ../verification/exp2/code/external_fields_load.F ../bin/

7  Configure and compile the code:    http://mitgcm.org/pelican/online_documents/node1.html
   cd ../bin  
   ../tools/genmake -makefile  
   make depend  
   make

 To run:  
   cd ../exe  
   cp ../verification/exp2/input/* .  
   dmpirun -np 4 mitgcmuv  ( Digital )

 There is comparison output in two directories:  
  ../verification/exp2/results  
  ../verification/exp2/results.oldcode  
   
 To obtain the "oldcode" numbers make the following changes  
 to the older code:  
 CPP_OPTIONS.h must have  
   #define OLD_ADV_BCS  
   #define OLD_UV_GEOMETRY  
 calc_mom_rhs.F must have  
   #undef  NO_LATERAL_SLIP  
   #define NO_BOTTOM_SLIP  
   
 Comments:  
 The input data is real*4.
