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 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
_R_a_t_f_o_r is best used with _f_7_7(1).
