Hi Amitabh,

I agree, it looks like a compiler problem.  Specifically, it looks like
your MIPSPro compiler is trying to treat the code as Fortran-90 when the
MITgcm model follows the Fortran-77 standard.

Heres two things that you can do:

 1) Try a different set of compiler options.  For instance, does 
    your MIPSPro compiler have an option to specify that its 
    working with Fortran-77 source, not Fortran-90/95?  Most modern 
    F90/95 compilers have such an option.

 2) Get a different compiler.  Theres at least one other compiler 
    (GNU g77) that will run on your SGI platform.  Is it installed?

Good luck,
Ed
