NAME
ratfor - ratfor preprocessor for Fortran 77
SYNOPSIS

PARAMETERS
-l n Set starting label number.
-o output
Specify output file; default is stdout.
-C Keep comments in (useful for compiler directives).
-? Show summary of options.
DESCRIPTION
Ratfor has the following syntax:
prog: stat
prog stat
stat: if (...) stat
if (...) stat else stat
while (...) stat
repeat stat
repeat stat until (...)
for (...;...;...) stat
do ... stat
switch (intexpr) { case val[,val]: stmt ... default: stmt }
break n
next n
return (...)
digits stat
{ prog } or [ prog ] or $( prog $)
anything unrecognizable
where stat is any Fortran or Ratfor statement, and intexpr is an expression that resolves into an integer
value. A statement is terminated by an end-of-line or a semicolon. The following translations are also
performed.
< .lt. <= .le.
== .eq.
!= .ne. ^= .ne. ~= .ne.
>= .ge. > .gt.
| .or. & .and.
! .not. ^ .not. ~ .not.
Integer constants in bases other that decimal may be specified as n%dddd... where n is a decimal number
indicating the base and dddd... are digits in that base. For bases > 10, letters are used for digits
above 9. Examples: 8%77, 16%2ff, 2%0010011. The number is converted the equivalent decimal value using
multiplication; this may cause sign problems if the number has too many digits.
String literals ("..." or '...') can be continued across line boundaries by ending the line to be
continued with an underline. The underline is not included as part of the literal. Leading blanks and
tabs on the next line are ignored; this facilitates consistent indentation.
include file
will include the named file in the input.
define (name,value) or
define name value
defines name as a symbolic parameter with the indicated value. Names of symbolic parameters may contain
letters, digits, periods, and underline character but must begin with a letter (e.g. B.FLAG). Upper
case is not equivalent to lower case in parameter names.
string name "character string" or
string name(size) "character string"
defines name to be an integer array long enough to accommodate the ASCII codes for the given character
string, one per word. The last word of name is initialized to the symbolic parameter EOS, and indicates
the end of string.
