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 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 continuation character x and places it in column 6.

Ratfor is best used with f77(1).
