Also use assumed shaped for dummy argument arrays where possible. If a Fortran procedure has an interface declaration, which includes all procedures exported from modules, then dummy arguments should be declared as assumed shape if possible. This allows compiler generated array bounds checking and compile time array shape checking. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@6456 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
