NAME
     ratfor - rational Fortran dialect

SYNOPSIS
     ratfor [ option ... ] [ filename ... ]

DESCRIPTION
     _R_a_t_f_o_r converts a rational dialect of Fortran into ordinary
     irrational Fortran.  _R_a_t_f_o_r provides control flow constructs
     essentially identical to those in C:

     statement grouping:
          { statement; statement; statement }

     decision-making:
          if (condition) statement [ else statement ]
          switch (integer value) {
               case integer:  statement
               ...
               [ default: ]   statement
          }

     loops:
          while (condition) statement
          for (expression; condition; expression) statement
          do limits statement
          repeat statement [ until (condition) ]
          break [n]
          next [n]

     and some syntactic sugar to make programs easier to read and write:

     free form input:
          multiple statements/line; automatic continuation

     comments:
          # this is a comment

     translation of relationals:
          >, >=, etc., become .GT., .GE., etc.

     return (expression)
          returns expression to caller from function

     define:
          define name replacement

     include:
          include filename

     The option -h causes quoted strings to be turned into 27H
     constructs.  -C copies comments to the output, and attempts

     to format it neatly.  Normally, continuation lines are
     marked with a & in column 1; the option -6x makes the con-
     tinuation character x and places it in column 6.

     _R_a_t_f_o_r is best used with _f_7_7(1).
