USAGE

ratfor [ options ] [ files ]

DESCRIPTION

Ratfor converts a rational dialect of FORTRAN into ordinary FORTRAN.  It provides control flow constructs essentially identical to those in C, as well as simplified syntax to make programs easier to read and write.  These constructs are described below:

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

free form input:
multiple statements/line; automatic continuation

comments:
# this is a comment.

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

return expression to caller from function:
return (expression)

define:
define name replacement

include:
include file

OPTIONS

−h Turn quoted strings into 27H constructs. 

−C Copy comments to the output and attempt to format it neatly. 

−6x Make the continuation character x and place it in column six.  Normally, continuation lines are marked with an ampersand (&) in column one.
