ovarrf Subroutine

  subroutine ovarrf(file,descr,varnam,value,output_flag)

    !! Routine to print out the details of a floating-point
    !! variable using 'F' format
    !! author: P J Knight, CCFE, Culham Science Centre
    !! file : input integer : Fortran output unit identifier
    !! descr : input character string : Description of the variable
    !! varnam : input character string : Name of the variable
    !! value : input real : Value of the variable
    !! output_flag : optional character
    !! This routine writes out the description, name and value of a
    !! double precision variable in F format (e.g.
    !! <CODE>-12345.000</CODE>).

    !  Arguments

    integer, intent(in) :: file
    character(len=*), intent(in) :: descr, varnam
    real(8), intent(in) :: value
    character(len=3), intent(in), optional :: output_flag

    !  Replace descr and varnam with dummy strings of the correct length.
    !  This counters problems that would occur if the two original strings
    !  were the wrong length.
