! $Log: TURB_RansZeroDummyCells.F90,v $
! Revision 1.5  2009/08/26 12:28:52  mtcampbe
! Ported to Hera.   Fixed logical expression syntax errors.  Replaced all
! IF (logical_variable)  with IF (logical_variable .eqv. .true.) as
! consistent with the specification.  Also changed: IF( ASSOCIATED(expr) )
! to IF ( ASSOCIATED(expr) .eqv. .true. ).   Intel compilers produce code
! which silently fails for some mal-formed expressions, so these changes
! are a net which should ensure that they are evaluated as intended.
!
