ratfor

RATFOR(1)						      General Commands Manual							 RATFOR(1)

NAME

       ratfor - rational Fortran dialect

SYNOPSIS

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

DESCRIPTION

       Ratfor  converts a rational dialect of Fortran into ordinary irrational Fortran.  Ratfor provides control flow constructs essentially iden-
       tical 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
	      next

       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

       Ratfor is best used with f77(1).
