New ARPS Coding Standards with Fortran 90

• ARPS Fortran 90 Migration - Reasons and Approach

• New standard for ARPS version 5.0 and later in Fortran 90.

• Example ARPS code in Fortran 90: solvq.f90 hand converted from Fortran 77 code solvq.f.
  Include files globcst.inc, bndry.inc and exbc.inc are converted to F90 modules globcst.f90, bndry.f90 and exbc.f90.

• Converting F77 code to F90 code: see what a converter like convert.f90 can do to solve3d.f. After applying the converter, we have solve3d.f90.

• Standard and conventions for pre-5.0 versions of ARPS in Fortran 77. Excerpted from ARPS 4.0 User's Guide.
