Looks good to me... does it work?
Another good habit is to enclose variables in test statements like this between "quotes". That way if one of the variables happens to be empty the statement logic will still work instead of your script terminating with an 'invalid syntax' error.

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).
